This page contains the full cast of human characters, alive or dead, who exist within The Smurfs: Light and Dark. They are organized in alphabetical order within their respective categories.
Heroes and Allies
- Brenda -- A small recurring character of the series. She is a young witch at the Witch Haven Conservatory who learned what it meant to be "good" thanks to the Smurfs. She once had a crush on Scruple and was his date to the Broomstick Ball, but lost she such feelings after realizing that he only liked her for her magic wand. She was last seen expressing her intentions of spiting him by someday becoming a powerful good witch.
- Count Tremaine -- The former leading knight under the Good King. He was Johan's role model and loyal friend before Johan had reached squire hood. His whereabouts are currently unknown.
- Dame Barbara -- A recurring secondary character. She is the Good King's Governess and personal caretaker for Princess Savina, with whom she is frequently accompanying. She does not take kindly to outsiders until they prove their worth in the castle.
- Denisa -- One of the smaller recurring good characters of the series. She is the daughter of Lord Balthazar's wealthy sister with a bubbly personality and an uncanny set of vocal chords. She has made friends with Sassette, so she finds her uncle and Gargamel's plans to destroy the Smurfs as wicked and cruel.
- Falla Cye -- The second female protagonist of the series who debuts in "The Thief of Boarsford." She is a teenage girl who supposedly ran away from a kingdom south of the Good King's castle and was thought to be the culprit behind a robbery in Boarsford. With help from Johan and Peewit, she proves her good name and is assigned by the King to help bring the real bandit(s) to justice. Since then, she has been granted a room in the castle and becomes friends with the boys.
- The Good King -- The primary ruling figure of the series. He rules his kingdom fairly and is beloved by his subjects, especially his family members. He considers Sir Johan like a son and would welcome anyone into his castle if the boy vouched in their favor, including vagabonds.
- Homnibus -- One of the main good wizards of the series. He is an old friend of the Smurfs, the Good King, and Johan and Peewit who is willing to lend his magical assistance whenever needed. He has an adopted son of whom he has yet to reveal his ways of sorcery -- although he intends to do so when he is of proper age.
- Jean de Baufort -- A lesser-known ruling figure of the series. Originally from Besdorf, Germany, Jean is the direct descendent of Aldebert Baufort and the rightful heir to the Baufort castle. Had it not been for Johan and Peewit's help against an army of conniving relatives, he would have surely joined his great-great-grandfather in the afterlife by the hands of his envious relatives.
- Sir Johan -- The keystone protagonist of the series. He is a young knight under the Good King who is often accompanied by his best friend, Peewit, on a series of adventures. His valiance and relentless efforts to bring justice to anyone who is suffering is what leads him to the many friends and foes he comes to know.
- Josten Lancaster -- One of the supporting protagonists of the series who debuts in "King Gerard's Squire." Being one of only three loyal pageboys remaining in King Gerard's castle, Josten sees any desire to pursue his interests in music as an act of cowardice. His kind nature, pretty face, and unusual health issues earn him more pestering than praise by his peers, so his self-esteem is a lower than average.
- Justin -- A recurring background character of the series. Once he was an unwilling street rat in the hands of his thieving guardian, but has been growing into a noble young man after being adopted by the Enchanter Homnibus. He is frequently in school or studying at home and has not yet been exposed to the realm of magic.
- Mrs. Sourberry -- One of the background characters of the series. She is the faithful caretaker of King Gerard and the Clockwork Smurf who fondly hopes the young king will find happiness and love in his future.
- Peewit -- The faithful comedic sidekick to the main heroes of the series. After Johan lands him a job as the Good King's court jester, he has been a loyal friend with a heart almost as big as his stomach.
- Prince Paestum -- A prince who only appeared in the Season 8 episode, "Lost Smurf." Like Nanny Smurf, he and his servant were trapped in Castle Captor for five-hundred years and essentially disappeared from his family lineage. Now that they are free, he is struggling to find his place in the modern world.
- Princess Savina -- The first main female protagonist of the series. She is the Good King's niece primarily seen in the watchful company of Dame Barbara. She is learning to be a "proper princess," but greatly admires Johan and Peewit, often hoping to join their adventures around the kingdom.
- Prince Theodore -- A lesser-known ruling figure of the series. After having been turned into a frog by his former court magician, he was saved from this fate (and a one-sided marriage with Lady Jasmine) by Smurfette, Poet, and Sassette. He also once hired Gargamel and Scruple as his new court magicians, which was a mistake he will not soon forget.
- Professor Bemire -- A Season 5-exclusive character of the series. He teaches Horticulture and plant-related magic classes at the Wizard's School due to his love of nature as a part of the Animal Magic program.
- Professor Zora -- A Season 5-exclusive character of the series. She is a green-skinned witch who teaches Morphology and both Beginners or Advanced Potion Making. She is considered a friend of the Smurfs who is sworn to secrecy in an effort to protect them from other humans who may bring harm to them.

- Chlorhydris -- A background character of the series. She was previously a cruel sorceress who aspired to destroy all love in the world, which was caused by the betrayal of her ex-best friend: Drusilla sought after Manfred the Magnificent, but he chose to marry Chlorhydris. Thinking she had been upstaged on their wedding day, Chlorhydris grew bitter from a broken heart, but with help from the Smurfs and beloved cherub, Cupid, she and Manfred were reunited twenty years later and miraculously rekindled their long-lost love.
- Gargamel -- One of the main villains of the series. Ever since he first saw the Smurfs, he has been determined to prove their existence to the Dean of Wizards at the same school he and his lowly apprentice, Scruple, were expelled from. After years of miserable defeat, he and his cat, Azrael, are willing to do virtually anything to destroy the Smurf Village -- regardless of the consequences.

- Hogatha -- A supporting antagonist of the series. She is a short and portly vain witch who seeks to perfect her appearance by having real hair, flawless skin, and stay on top of the latest fashion trends. She also craves romance and power as shown by her attempts to convince important men (especially her crush, Lizardo) to marry her. At times, her endeavors call for use of the Smurfs, making her less threatening than Gargamel yet still a formidable villainess.
- Sir Jacob -- A formidable antagonist of the series. He is set to debut in "Josten's Dark Horse."
- Lady Jasmine -- One of the lesser-known females of the series. She was once engaged to Prince Theodore, but only liked him for his wealth. Had it not been for her deep-rooted fear of frogs and the intervention of the Smurfs (unbeknownst to her), she would have succeeded with her plan.
- Lady Prisca -- A late-introduced character of the series. She is Lord Balthazar's sister and the mother of Denisa who wants to claim her brother's wealth and powers for herself. She is set to debut in "My Kingdom for a Crook."
- Lord Balthazar -- A prominent antagonist of the series. He is Gargamel's Godfather, a powerful sorcerer, and a wealthy Lord who strives to be ahead of the curve when it comes to what the future holds so that he will maintain his self-proclaimed title as "the most powerful sorcerer in the world."
- Queen Gwendolyn -- A queen from an unknown kingdom who only appears in "Queen Smurfette" on her way to King Gerard's castle. She is set to debut in The Goblet of Eternal Servitude.
- Scruple -- One of the main antagonists of the series. He is a redheaded child who recognizes that his former professors assigned him as Gargamel's apprentice simply to avoid having to expel him on the school records. Fearful of following in his master's footsteps, the boy is desperate to return to school and graduate. He might believe in his future if someone else believed in him, too.
- Willum -- A small recurring character of the series. He is a portly brunette student with freckles at the Wizard's School and one of Scruple's former classmates who now bullies him for being a dropout. He is often seen in the company of his friends, Giles and Cedrick.

- Falla's Parents -- They are seldom mentioned by Falla herself, but they will be revealed in the Season 4 Finale, Infallible Judgement.

He is a relatively vain wizard who seems to value anything of conventional beauty such as one's beautiful singing, hair, fashion style, fiscal wealth, and power (whether magical or by social status). He once set his sights on Hogatha only to ditch her upon discovering that she was bald, hence her increased desire to have real hair thereafter.
