"How Am I Supposed to Live Without You" is a song written in 1983 by Doug James and Michael Bolton. The ballad has been recorded by many artists around the world, in several languages, becoming something of a modern pop standard. Instrumental versions of the song have been recorded featuring variously the piano, guitar, saxophone, pan flute, steel drum, and music box.

"How Am I Supposed to Live Without You" was supposed to be recorded by the duo Air Supply. But when Arista President Clive Davis asked for permission to change the lyrics of the chorus, Bolton refused, and Davis released the song. Subsequently Laura Branigan recorded it as written, and it became the first major hit for the two songwriters. The song was also performed by actress Lisa Hartman on the soap opera Knots Landing. Bolton's own rendition became a worldwide hit in early 1990.

As the second single from Branigan's second album Branigan 2, "How Am I Supposed to Live Without You" spent three weeks at number one on the Billboard Adult Contemporary chart and peaked at number twelve on the Hot 100 in early October 1983. Branigan's single also hit the number one spot on the Adult Contemporary chart in Canada. This success came without benefit of a music video. Branigan performed the song on the syndicated music countdown show Solid Gold in late 1983 and on the popular holiday special Dick Clark's New Year's Rockin' Eve. Branigan 2 went out of print in 2004, but Branigan's original version can still be heard on the compilation albums The Best of Branigan (1995), The Essentials (2002) and The Platinum Collection (2006).
