"Don't Fight It" is a rock song performed by Kenny Loggins and Steve Perry, the lead singer for Journey at that time.

Loggins has described the song as 'an experiment in pushing my limits to include rock', from the liner notes of his 1997 compilation Yesterday, Today, Tomorrow.

According to Loggins, the bullwhip sound effect in the song was created using a whip that was also used for the Indiana Jones movies.

It peaked at number 17 on the US Billboard Hot 100 and #15 on the Cash Box Top 100.

It was nominated for Best Rock Performance by a Duo or Group with Vocal at the 1983 Grammy Awards.
