K'NEX

 is an American-made building toy created by Joel Glickman and originally released in 1993 by K'NEX Industries. The K'NEX building system involves mostly using rods, connectors, gears, and other components which "snap" together to create models, however, for a few years until 2019, some K'NEX sets used building bricks similar to that of LEGO.

Between 2011 and 2017, K'NEX produced licensed sets based on the Super Mario franchise. Sets have been made based upon several games, starting with Mario Kart Wii and later expanding into Mario Kart 7, Super Mario 3D Land, New Super Mario Bros. 2, New Super Mario Bros. U, Super Mario 3D World, and Mario Kart 8. Several sets have also been made not specifically based on any game, simply using the "Super Mario" branding.

Following the purchase of the brand by toy company Basic Fun! in February 2018, the company ended all production on licensed and brick-based sets, including their Super Mario theme, and has since focused strictly on generic sets. In March 2020, it was announced that LEGO had acquired the rights to produce Mario-themed construction sets.
