Nanalan' is a Canadian children's television series created by Jamie Shannon and Jason Hopley. It began in 1998 as a series of three-minute shorts originally broadcast on YTV; it later ran for two seasons of full-length (21 minutes) episodes that were first broadcast by CBC. The series chronicles the small-scale adventures and discoveries of a three-year-old puppet girl named Mona in her grandmother Nana's backyard. The title is a contraction of the phrase "Nana Land," referring to the setting.

Hopley and Shannon produced the series through their puppetry troupe The Grogs in association with Lenz Entertainment. The show uses a blend of hand puppetry and the manipulation of cardboard cutouts, particularly in the opening theme. While the shorts do not follow a structure, the half-hour episodes follow a loose format that includes at least one song or reading an original story to the viewers.

The show received three nominations at the 2004 Gemini Awards and was fairly well received by Canadian and U.S. press, with some critics calling attention to the show's surreal presentation and genuine approach to its concept. In 2004, select shorts were released across several DVDs and VHS in the U.S. In the mid-2010s and early 2020s, the series went viral with a resurgence in popularity on websites such as Tumblr and YouTube for its bizarre nature.

Interest in the series was renewed in late 2023 after video clips of it went viral on TikTok. The new success led to Hopley and Shannon reuniting for the first time since disbanding The Grogs in 2009, reprising Nana and Mona for interviews and online videos.
