Aladdin and the King of Thieves (also known as Aladdin 3: The King of Thieves) is a 1996 American direct-to-video animated musical fantasy adventure film produced by Walt Disney Television Animation. It is the second sequel to Disney's 1992 animated feature film Aladdin, and it serves as the final chapter and installment of the Arabian Nights-inspired Disney franchise beginning with the first film, and continuing with its first direct-to-video sequel The Return of Jafar and the animated television series.

The film takes place after the third season of the television series and is inspired by the tale Ali Baba and the Forty Thieves from One Thousand and One Nights, replacing Ali Baba with Aladdin. For the first time since the original Aladdin, the film has a completely new soundtrack instead of the rearranged music from the original film for The Return of Jafar and the series. This film also marks the return of Robin Williams, reprising his role as Genie (Dan Castellaneta voices him in the second film, the series and other media).

Although this film serves as the series finale of the television series, the characters also appear in a 1999 crossover episode of the animated series Hercules, titled "Hercules and the Arabian Night", as well as the segment More Than a Peacock Princess from the 2007 direct-to-video film Disney Princess Enchanted Tales: Follow Your Dreams, both of which occur after this plot. The film received mixed-to-negative reviews, although it was deemed an improvement over The Return of Jafar.
