"This Could Be the Night" is a song recorded by the American band Modern Folk Quartet (MFQ) in late 1965 or early 1966. The lyrics describe a couple on the verge of conquering their inhibitions. Written in tribute to Beach Boys leader Brian Wilson, the song is one of three that are credited jointly to Harry Nilsson and Phil Spector, although Nilsson submitted that he was the sole writer on a 1966 copyright form.
