"Don't Let Him Go" is a song written by Kevin Cronin. It was originally released as the opening song for REO Speedwagon's #1 album Hi Infidelity. It was also released as a single, reaching #24 on the Billboard Hot 100 chart. "Don't Let Him Go" has appeared on several REO Speedwagon greatest hits albums.

Like the #1 single from Hi Infidelity, "Keep on Loving You," the lyrics of "Don't Let Him Go" are about breaking up with a longtime girlfriend. According to Joseph Timmons of Seattle Post Intelligencer, the song is a "warning to not take the man you love for granted." Casandra Armour of vintagerock.com described the lyrics as having the singer pleading on behalf of a friend who has "a lot of swag but not much substance" but "just needs a chance to grow."Allmusic critic Stephen Thomas Erlewine remarked on the song's "insistent beat." He and other critics have also pointed out that the song was influenced by Bo Diddley. Author Chuck Eddy described it as a "Bo Diddleyed do-si-do." Armour describes the music as "a jaunty kind of hand-jive peppered with power chords." Pete Bishop of The Pittsburgh Press described "Don't Let Him Go" as a "straight-ahead melodic rocker."Allmusic critic Barry Weber described the song as an "underrated rocker."

"Don't Let Him Go" was also included on the compilation albums The Hits and The Essential REO Speedwagon. A live version was included on The Second Decade of Rock and Roll, 1981-1991, Arch Allies: Live at Riverport, and Setlist: The Very Best of REO Speedwagon Live. In 1981, the band performed the song on the television show America's Top 10.
