Along with their many anthology programs such as Oh Yeah! Cartoons and KaBlam!, both Nickelodeon and Nick Jr. have aired many different types of shorts between their programs by a variety of young people, in-house, and even by kids over their 20+ year history. The shorts have had premises revolving around everything from singing food, turning inside out, the alphabet, and lots more. A number of shorts based on their beloved Nicktoons have also been made.
Some notable shorts and interstitials on Nickelodeon include:
- Short Films by Short People: A series showcasing shorts created by kids, and included interviews with the kids who created them and behind the scenes looks at their shorts. Among these shorts are Foil Man and Attack of the Giant Vulture.
- Inside Out Boy: Stop-motion. A series of shorts about a boy who swung all the way around the swing-set one day and gained the ability to turn himself inside out as a result. Four shorts were spread across the first two Rugrats VHS releases (Tales From The Crib and A Baby's Gotta Do What A Baby's Gotta Do) in 1993 in-between episodes on the tapes.
- The Non-Adventures Of Safety Queen: Traditional animation. A kid who is having a problem accomplishing a difficult or possibly hardest task gets visited by a strange girl known only as the Safety Queen. The Safety Queen helps motivate the kid by using reverse psychology, explaining to the kid why they shouldn't finish the task at hand, citing a number of absurd or outlandish outcomes of going through with it. Invariably, the kid goes through with it and finds that what they were trying to do wasn't so difficult after all. One example. Three shorts were included on the 1996 Rugrats VHS Phil And Lil: Double Trouble, playing in-between episodes.
- The Off-Beats: Traditional animation. Originally played during commercial breaks in late 1995 to early 1996 before it became part of KaBlam!'s lineup in Fall 1996 and aired on the show for the first two seasons (the original pre-KaBlam! shorts would continue to play until late 1997). It eventually got its own Valentine's Day special in 1999. Thee shorts were included on the 1996 Rugrats VHS Tommy Troubles, playing in-between episodes.
- CatDog: Traditional animation. Originated as a series of pilot shorts before the series premiered. One short, "Fetch!", was also attached to The Rugrats Movie as a sneak peek (a another short, "Winslow's Documentary", was attached to the movie's VHS and DVD)
- The Adventures of Jimmy Neutron, Boy Genius: 3D Computer-generated animation. Originated as a series of shorts made to hype his movie. Later became a series as well.
- Mr. Meaty: Puppets. This originated exclusively as shorts airing between shows on the channel before becoming greenlit for a full-on series.
- Astrology with Squidward: SpongeBob SquarePants' nasty sealord Squidward Tentacles explains the Western Zodiac during different times of the year. He describes the behaviors of people of each symbol, and he predicts their future lives. The zodiac symbols are based off of other SpongeBob SquarePants characters.
Shorts from the various anthology shows often aired between shows during normal Nickelodeon programming as well.
Some notable shorts and interstitials that aired on Nick Jr. include:
- Face: From 1994 to 2004, the Nick Jr. block was hosted by a smiley face on a color-changing background, who engaged in humorous antics before announcing the next show or ad break. Face was given a revamp in 2003 that only lasted for a couple months before he reverted to his original design and eventually was phased out. Voiced in the US by Chris Phillips, and in the UK by David Holt. In 2022, Face would be rebooted again as the host of Face's Music Party, this time voiced by Cedric L. Williams in English.
- Amby & Dexter: Traditional animation. A pair of hands doing something boring such as playing the piano or going out the door turn into two small people who accomplish the task in a way that two dwarf-sized people would do it. One short featuring the two painting a picture.
- Countin' Carl: Live-action. A strange man in a superhero outfit rides a bicycle around the neighborhood and helps kids with their counting skills.
- Joey's Lunch: Stop-motion. Talking food come out of the unseen Joey's lunchbox and do silly things or sing a song. Usually ended with one of the food characters asking the viewer if they had ingested a certain food today.
- Maggie and the Ferocious Beast: Traditional animation. A little girl's adventures with the eponymous Ferocious Beast (who isn't really that ferocious at all). Later became a full-on series.
- Max And His Alphabet Adventures: Traditional animation. Before going to bed, young Max talks about the oddly alliterative adventures he goes on with 26 letters of the alphabet. Every short ended with the adventure suddenly being interrupted by Max's dad reminding Max to go to sleep. An example with Max visiting the letter T.
- Oobi: Puppets. The first season was a series of interstitials that aired during commercial breaks on Nick Jr. and Noggin. It was later developed into a long-form show that played on Noggin for many years.
- Nanalan': Puppets. A series detailing the antics of 3-year-old Mona as she spends the day at her Nana's house.
- Winky Love: Traditional animation. A girl talks about what it's like living in the big city and what she does there. Notable for having an African-American female protagonist.

- Advice Backfire: Played with in the "Safety Queen" shorts. Safety Queen's wild, sarcastic advice leads to the person solving their problem easier than they thought they would.
- An Aesop: Par for the course with the Nick Jr. shorts, though some were just plain fun for the sake of being fun.
- Attack of the 50-Foot Whatever: Well, not fifty-foot, but still larger than normal, there's the vulture in the Short People short "Attack Of The Giant Vulture".
- Big Applesauce: The city that Winky Love lives in strongly resembles New York City, but it's never stated that it is New York.
- Birthday Episode: The Max episode revolving around the letter B revolved around Max's birthday. Technically it would be a "Night-Before-Birthday-Episode" as Max's dad reminds Max that tomorrow is his birthday after reminding him to go to sleep.

- Captain Obvious: Most of the "predictions" made by Squidward in Astrology with Squidward are facts that were inevitably going to happen anyway.
