"Somebody's Knockin'" is a song recorded by American country music singer Terri Gibbs. It was released in October 1980 as her debut single and title track from her album Somebody's Knockin'. It was co-written by Jerry Gillespie and Ed Penney. Penney was a record company executive who liked Gibbs's voice when he first heard her audition tape, but felt she needed stronger material. Penney was a former Boston disc jockey who had promoted records and written a number of songs before moving to Nashville. He was the producer of "Somebody's Knockin'" and became Terri Gibbs's manager.
