Nick at Nite international versions
Despite the success of Nick at Nite in the United States, most international versions of Nickelodeon do not carry their own Nick at Nite programming block, as those local versions of Nickelodeon outside of the United States either carry children's programming 24 hours a day or run a non-Nick at Nite program block during the nighttime hours. While Nick at Nite's U.S. flagship primarily focuses on reruns of discontinued primetime network sitcoms, some of these international versions have aired reruns of discontinued Nickelodeon series.
As of 2023, Australia is the only country outside the United States to have a Nick at Nite block.
Latin America
Nick at Nite launched on February 13, 2006 in Latin America and Brazil. Until 2012, the network had aired shows such as ALF, Mork & Mindy, The Addams Family, The Munsters, Bewitched, I Dream of Jeannie, Happy Days, The Fresh Prince of Bel-Air, Growing Pains, The Facts of Life, Diff'rent Strokes, Get Smart and Perfect Strangers, which have been broadcast on other Latin American broadcast and cable channels. Although the Latin American Nickelodeon was launched in the mid-1990s, it had never carried the Nick at Nite block before; as of April 2010 the Latin American version had since shifted away from classic and defunct Nickelodeon series, between animated series and live-action comedies such as Zoey 101, Ned's Declassified School Survival Guide, True Jackson, VP, Hey Arnold!, Rocko's Modern Life and Rocket Power. The block was abruptly ended on January 1, 2015 after almost 9 years.Australia and New Zealand

Europe
UK and Ireland
Nick at Nite’s UK and Ireland feed was one of the planned, and advertised, stations as part of Sky's new Multichannels package, but it never launched. However, it was announced in June 2016 that a UK version of Nick at Nite would finally launch on Nickelodeon UK on June 27, 2016, running from 7pm to midnight/12am.Shows that were put in this slot include iCarly, Victorious, Sam & Cat and Drake & Josh. In 2019, the Nick at Nite branding was wiped off, so the night-time programming on the channel once again runs under the main Nickelodeon branding.
Germany, Austria and Switzerland
In Germany, Nick nach Acht was a programming block aired on Nickelodeon Germany after 8:15 p.m. CET starting on January 1, 2008. It aired documentaries, drama series, movies and sitcoms. The block used an adapted version of the then-current logo of its American counterpart. Many parts of the block included reruns of Ren and Stimpy and CatDog. These shows were only available on Nick Germany's website, though. Starting on December 15, 2008, Nickelodeon and Comedy Central shared the same channel space; Comedy Central aired after 8:15 p.m., effectively replacing Nick nach Acht.In July 2014, it was announced Nickelodeon would become a 24-hour-channel once again. The overnight schedule would be branded as "NickNight", a block which launched on October 1, 2014. The block ran from 9:00pm to 5:45am CET and featured classic Nickelodeon programming along with a selection of series from MTV and other programming for a teenage audience. In preparation for the move, Comedy Central moved to the channel space of VIVA in September 2014, where it initially broadcast from 5pm to 6am; this changed in October 2015 so that Comedy Central now ran on VIVA's space from 2pm to 2am. Nicknight was replaced by MTV+, a one-hour timeshift of MTV, on November 1, 2018. MTV+ broadcasts between 8:15pm and 5:00am. Later on March 1, 2021 MTV+ was canceled for the new one-hour timeshift of Comedy Central. Comedy Central+1 runs from 8:15pm to 1:00am. At 1:00am starts Nick Germany.
Netherlands
In the Netherlands, Nick@Nite aired on Nickelodeon from mid 2004 to early 2005, as Nickelodeon got access to airing 24 hours a day. It mostly aired Nickelodeon programmes with their original language, but at midnight they would often show vintage children's programmes such as Bassie en Adriaan, De Bereboot and Calimero. The animated series Argaï was only aired during these hours on the channel.Nick@Nite ran for the lifespan of their 24/7 channel. Its run in the Netherlands ended in 2005, when Nickelodeon began having to share its channel space with Talpa. As a result, they decided to move to the channel occupied by The Box, first sharing with The Box and later sharing it with the Dutch version of Comedy Central. Nickelodeon became a 24-hour service again on February 14, 2011, and on that day, TeenNick premiered on the channel, which resembled the original Nick at Nite form as used between 2004 and 2005. TeenNick was replaced by a Dutch version of Spike on October 1, 2015.
