Jonathan Blow (born 1971) is an American video game designer and programmer. He is best known for his work on the independent video games Braid (2008) and The Witness (2016). Blow became interested in game programming while at middle school. He studied computer science and English at the University of California, Berkeley, but dropped out to start a game company. After the company closed following the dot-com crash, Blow worked as a game development contractor. He co-founded the Experimental Gameplay Workshop and wrote a monthly technical column for Game Developer magazine.

Blow gained prominence in 2008 with Braid. He used its financial success to fund his next game, The Witness, and formed a company called Thekla Inc. After a lengthy development period, The Witness was released in 2016, and like Braid was critically and financially successful. During its development, Blow became frustrated with C++, the computer language Thekla used to create the game. He began designing and creating a new programming language. Full-time work on the language, code-named Jai, and a new game implemented in it began after the release of The Witness. A compiler for the Jai language is currently in beta release.

Blow's games are known for being artistic and challenging. They are made with custom game engines, and have larger budgets and longer development times than most independently funded games. Blow was featured in Indie Game: The Movie, and is known for his strong opinions about the gaming industry.
