Daniel Richard Powter is a Canadian musician. He is best known for his self-penned hit song "Bad Day" (2005), which was at the top of the Billboard Hot 100 for five weeks.

"Bad Day" is a pop song by Canadian singer-songwriter Daniel Powter from his self-titled second studio album (2005). It was written by Powter and produced by Jeff Dawson and Mitchell Froom. Powter and Dawson recorded the song in 2002, but were initially unable to find a record label to release it. The song was first used in a French Coca-Cola television advertisement in Christmas 2004 before its official release. Tom Whalley, Warner Bros. Records' chairman and CEO, offered Powter a contract after hearing a demo tape of it. This track ended up being released as the aforementioned album's lead single in Europe in early 2005.
