"(If You're Not in It for Love) I'm Outta Here!" is a song co-written and recorded by Canadian country music singer Shania Twain. It was released in November 1995 as the fourth single from her album The Woman in Me. The song was written by Mutt Lange and Twain. The song became Twain's second number-one hit at country radio, and the first single to be promoted with three different mixes worldwide to cater to international genre demand. It spent two weeks at the top of the chart in February 1996. The song was also her breakthrough hit in Australia. "(If You're Not in It for Love) I'm Outta Here!" was later included on Twain's 2004 Greatest Hits package, and has been performed on all of her tours.
