Howard Kern Day (born in Bangor, Maine) is an American singer-songwriter. Beginning his career as a solo artist in the late 1990s, Day became known for his extensive touring and in-concert use of samplers and effects pedals in order to accompany himself. He self-financed and self-released his first album, Australia, in 2000.

Day signed to the major label Epic Records in 2002 and has since re-released his debut as well as producing a follow up, Stop All The World Now. Despite initially sluggish sales, Stop All The World Now was certified gold in early 2005 and has produced a number of singles, including "Collide", Day's most successful to date, and the hit "She Says".

Day has received significant negative attention over two high profile arrests. In 2004, Day was arrested and charged over an incident in which he was accused of locking a fan in the bathroom of his tour bus and destroying the cellular phone of another, for which he was fined. In December 2005, Day was arrested in Boston after reportedly verbally abusing the flight crew while under the influence of alcohol and sleeping pills. He was sentenced to one year's probation on April 26, 2006.
