List of Lilo & Stitch: The Series episodes

Lilo & Stitch: The Series is an American animated television series produced by Walt Disney Television Animation that aired for 65 episodes over two seasons. Bookended by the animated films Stitch! The Movie (2003) and Leroy & Stitch (2006), it first aired between the ABC Kids programming block and Disney Channel from 2003 to 2006. It is the first television series in the Lilo & Stitch franchise and a sequel to the 2002 animated film Lilo & Stitch. In this series, Hawaiian girl Lilo Pelekai and her alien best friend and adopted "dog" Stitch adventure around the island of Kauai searching for, naming, and rehabilitating Stitch's predecessor "cousins", who are his creator Dr. Jumba Jookiba's 625 other genetic experiments.

Note that Stitch, Experiment 626, appears in every episode, so he is not included in the "Experiments mentioned" list. Experiments' numbers are based on those seen in the list of experiments shown in the credits of Leroy & Stitch. In addition, Reuben, Experiment 625, wasn't named until Leroy & Stitch and was only referred to as "625" throughout the show; his later-given name is only shown in the "Experiments mentioned" list for convenience. Some experiments were given incorrect numbers in certain episodes; these and other discrepancies are noted below.

Notes

1. 28 segments; the episodes "Mrs. Hasagawa's Cats / Ace" and "Glitch / Woops" each contain two 11-minute segments
2. Hammerface was misnumbered 124 in Stitch! The Movie and referred to as "Hammerhead" by Pleakley in "The Asteroid".
3. Mis-numbered 119 in the episode.
4. Mis-numbered 458 in the episode.
5. Mistakenly referred to as 515, the number of Deforestator, in the episode.
6. Mis-numbered 349 in the episode.
7. Mis-numbered 350 in the episode.
8. Mis-numbered 239 in the episode; this experiment does not appear until Leroy & Stitch.
9. The U.S. copyright registrations of "Spike" and "Frenchfry" both list their production codes as 201, with the registration for "Spike" not showing the episode's title. It is presumed that 201 applies only to "Spike" while the production code for "Frenchfry" is actually 204 unless further evidence proves otherwise.
10. Tickle-Tummy did not have her number stated in either Lilo & Stitch: The Series or Leroy & Stitch, and was accidentally left off the experiments list in the latter. The Stitch! anime series has since confirmed that the experiment's number is 275, while Wormhole, who was initially given 275 in Leroy & Stitch and also later appeared in the anime, is now numbered 272.
11. Leroy was not given a number in his debut. He was eventually given the number 629 in June 2020 via a Disney Tsum Tsum-themed side story of the manga Stitch & the Samurai.
