Cinderfella is a 1960 American semi-musical comedy film adaptation of the classic Cinderella story, with most characters changed in gender from female to male and starring Jerry Lewis as Fella. It was released on November 22, 1960, by Paramount Pictures.

When Fella's father dies, he continues to live with his wicked stepmother Emily and her two sons, Maximilian and Rupert. His stepfamily takes over the family mansion, while Fella is reduced to living in an unfinished room at the end of a long hallway. He has essentially become their butler, catering to their every whim.

Fella dreams nightly that his father is trying to relay a message to him about where he has hidden his fortune, but he always awakens before he learns the hiding place. His stepfamily knows of this secret fortune and some go to great lengths to discover its whereabouts, while others pretend to befriend him in order to wrangle Fella's fortune away once it is found.

Princess Charming of the Grand Duchy of Morovia is in town, so the stepmother decides to throw her a lavish ball in order to get her to marry Rupert. Fella is not allowed to go to the ball, but his fairy godfather says he will not remain a "people" much longer, but will blossom into a "person."

Before the ball, Fella is turned into a handsome prince. Count Basie's orchestra is playing at the ball when Fella makes his grand entrance. Fella quickly gains the attention of the princess and they dance. The night is cut short when midnight strikes and Fella flees, losing his shoe along the way.

Back home, one of Fella's stepbrothers realizes that Fella is the supposed "prince." They wind up in a struggle under a tree and discover that the fortune is hidden there. Fella, who had always known where the money was, gives it to his stepfamily, saying that he never needed money to be happy; he only wanted a family. Shamed, his stepmother orders her sons to return the money to Fella.

The princess arrives with Fella's lost shoe, but Fella explains that they could never be together because she is a "person" and he is a "people." She tells him that, underneath the fancy clothes, she is a "people" too.

Cinderfella was filmed from October 19 through December 15, 1959.
