"Let Her In" is a song written and recorded by English singer-songwriter Gary Benson, and released as a single in 1973.

In Canada, "Let Her In" reached number seven on the RPM Top Singles chart.

"Let Her In" was released at the end of the first year of the four-year run of Welcome Back, Kotter, in which Travolta starred.

Tom Breihan criticized Travolta's performance of "a moony and generic song" in his December 2019 Stereogum article and later called it "truly wretched" in his January 2020 A.V.

[12][13] Paul Grein of Billboard in August 2022 called the ballad "mopey".
