Level-5 Inc. is a Japanese video game developer and publisher based in Fukuoka, who are best known for their Professor Layton, Inazuma Eleven, Ni no Kuni, and Yo-kai Watch franchises. The company was founded in October 1998 by Akihiro Hino after he departed from the now defunct Riverhillsoft.

Early in its history, the company enjoyed a close relationship with Sony Computer Entertainment, with many of its titles funded by and produced in conjunction with them. Starting in 2007, the company started self-publishing its titles in Japan, while Nintendo took over publishing on their systems internationally. By the early 2010s, Level-5 was one of the ten largest video game companies in Japan, holding a market share of 3.2%.
