SNICK (short for Saturday Night Nickelodeon) was a two-hour programming block on the American children's cable television network Nickelodeon, aimed towards preteen and teen audiences, older than the target audiences of most Nickelodeon programming. It ran from August 15, 1992, until January 29, 2005 and was aired on Saturdays starting at 8 p.m and ending at 10 p.m. ET, with a replay on Sundays from 5 p.m. to 7 p.m. In 2005, SNICK was revamped as the Saturday night edition of TEENick. Nickelodeon continued to run a Saturday night programming block until 2021, although since the TEENick name was discontinued in February 2009, the block did not go by any name, with the exception of Gotta See Saturdays in fall 2012.

At the time of SNICK's creation, traditional networks such as ABC, NBC, and CBS did not have a specific programming block for younger viewers on Saturday nights. The consensus at the time was that viewers who were 50 years of age and older were the only ones watching available, since younger viewers traditionally went out on Saturday nights. This would explain why shows such as NBC's The Golden Girls and Empty Nest were the most predominant shows on Saturday nights at the time. Previously on Saturdays, Nickelodeon themselves had the Saturday night timeslot to older sitcoms from the channel's late night programming block, Nick at Nite.

Then-Nickelodeon president, Geraldine Laybourne, wanted to expose the myth that there was no audience for children's programming on Saturday nights. Laybourne was a purveyor of market niche-talk, which was a strategy of programming highly focused programs targeted to specific groups defined by age, gender, race, education, religion or any of a number of other factors. In theory, the audience who would most likely watch SNICK would be too young to be out on the town and too old to be in bed by eight.

Laybourne believed that the original shows on the SNICK block would double Nickelodeon's audience on Saturday night by as many as 650,000 to one million viewers. According to Nickelodeon, about one-third of Ren & Stimpy's audience, more than a million viewers, were between the ages of 18 and 35. By early 1993, Nickelodeon (according to A.C. Nielsen ratings) was the number one network among viewers ages 6–11 on Saturday nights. With a 6.4 age-group rating, Nickelodeon beat Fox's 5.5, NBC's 5.2, CBS' 4.8, and ABC's 3.2 ratings.

SNICK debuted on August 15, 1992, with two programs that previously aired on Sundays (the teen sitcom Clarissa Explains It All and The Ren & Stimpy Show) and the network premieres of Roundhouse (a musical sketch comedy-variety series) and Are You Afraid of the Dark? (a horror fantasy-drama anthology series).

Three new shows (The Adventures of Pete and Pete, The Secret World of Alex Mack, and All That) premiered on the block between 1994 and 1995, with the latter two replacing Clarissa and Roundhouse's time slots, which both shows had ended their runs. By this time, much of SNICK's programming had diversified to the point of making room for other new programs by replacing their existing shows or scheduling them in different time slots.

On some occasions, the block would run a series of interstitial shorts in-between regular broadcast, known as "SNICK Snack", or special programming events.

Many bumpers and advertising promos for SNICK featured the programming block's mascot, dubbed "The Big Orange Couch," in several places, including in different Nickelodeon shows (front of the Midnight Society's campfire, Ren and Stimpy's house, the Roundhouse, among others), as well as various real life and fictional locations.
