"Just One Look" is a song co-written by American R&B singers Doris Troy and Gregory Carroll. The recording by Doris Troy was a hit in 1963. The Hollies, Anne Murray and Linda Ronstadt recorded hit versions of their own. There have also been many other versions of this song.

Details vary as to how the Doris Troy version came to be released on Atlantic Records. According to the book Billboard Book of One-Hit Wonders,James Brown saw Troy performing in a nightclub (under her then-stage name Doris Payne), and introduced her to Atlantic. According to a more recent and detailed story in Soulful Divas, Payne recorded a studio demo of the song and took it to Sue Records first, but their lack of response led her to offer it to Jerry Wexler at Atlantic, where the label released the demo unchanged. The personnel on this song included Ernie Hayes on piano, Wally Richardson on guitar, Bob Bushnell on bass and Bernard Purdie on drums.

In 1963, Doris Troy scored her only hit on the U.S. Billboard Hot 100 chart with "Just One Look". The song spent 14 weeks on the Billboard Hot 100, peaking at No. 10, while reaching No. 3 on Billboard's Hot R&B Singles chart, No. 8 on New Zealand's "Lever Hit Parade", and No. 1 on Canada's CHUM Hit Parade. The single's release was the first time she started using "Doris Troy" as her stage name, though her pen name remained Doris Payne. The album also lists the surname Payne in the songwriting credits.
