Daniel Stewart Butterfield (born 1973) is a Canadian entrepreneur and businessman of Polish descent, best known for being a co-founder of the photo sharing website Flickr and team messaging application Slack.

Butterfield was born in Lund, British Columbia in 1973 to Norma and David Butterfield. His grandfather came from Poland to Canada at age 17 at interwar period. He was educated at St. Michaels University School in Victoria, British Columbia. He received a B.A. degree in philosophy from the University of Victoria in 1996. Butterfield went on to earn a Master of Philosophy from the University of Cambridge in 1998, where he specialized in the philosophy of biology, cognitive science, and the philosophy of mind.

In the summer of 2002, he co-founded Ludicorp in Vancouver with Caterina Fake and Jason Classon. Ludicorp initially developed a massively multiplayer online role-playing game called Game Neverending. The game did not launch, but the company then started a photo-sharing website called Flickr. In March 2005 Ludicorp was acquired by Yahoo!, where Butterfield continued as the General Manager of Flickr until he left Yahoo on July 12, 2008.

In 2009 Butterfield cofounded a new company called Tiny Speck. Tiny Speck launched its first project, the massively multiplayer game Glitch, on September 27, 2011. Glitch was later closed due to its failure to attract a sufficiently large audience. The game world closed down on December 9, 2012, but the web site, with most of the content, is still available. In January 2013, it was announced that the company would make most of the game's art available under a Creative Commons license. On December 9, 2014, a fan project to relaunch Glitch under the name Eleven began alpha testing.
