"Suspicions" is a country music song. It was originally recorded and released as a single in 1979 by Eddie Rabbitt from his album Loveline; his version was a Number One hit on the Billboard country music charts and a Top 20 hit on the Billboard Hot 100. The song saw renewed popularity in late 2007-early 2008, when Tim McGraw recorded and released a cover version on his album Let It Go.

The song was the first single from Rabbitt's 1979 album Loveline, "Suspicions" reached No. 1 on the Billboard Hot Country Singles charts that August. "Suspicions" also continued Rabbitt's rise as a crossover artist; peaking at No. 13 on the Billboard Hot 100, it was his highest peak on the pop chart to that time.

Rabbitt said that he wrote the song "in five minutes in the studio during a lunch break".

"Suspicions" was named Broadcast Music Incorporated's Song of the Year a year later.

In 2007, country music artist Tim McGraw recorded a cover of "Suspicions" for his album Let It Go. McGraw's cover of the song originally charted at number 56 in early 2007 from unsolicited airplay received shortly after the release of Let It Go.

Ken Tucker of Billboard described McGraw's cover positively, saying that McGraw sings "like a man who knows what it's like to have heads turn when your wife walks into the room".

McGraw's version was released on November 26, 2007 the fourth single from this album (counting "If You're Reading This", only available on later presses). The cover version peaked at 12 on the Billboard Hot Country Songs charts in February 2008, becoming the second Top 40 hit of Tim's career to miss the Top 10.
