Circle of One is the third album by American vocalist, pianist, and songwriter Oleta Adams and was released on May 14, 1990, in Europe and on June 19, 1990, in the United States. Circle of One was Adams' first album to receive wide distribution; her two earlier albums (an untitled album in 1982 and Going on Record in 1983) were self-financed and received only local distribution.

After a successful collaboration with Tears for Fears on their 1989 album The Seeds of Love, Adams was offered a record deal of her own with Tears for Fears then-label Fontana Records. Produced by Tears for Fears' Roland Orzabal with Dave Bascombe, the album was initially unsuccessful (peaking at no.49 in the UK) as were the first two singles "Rhythm of Life" and "Circle of One". However, Adams had a hit in early 1991 with the third single from the album, her cover of Brenda Russell's "Get Here," which peaked at #4 in the UK Singles Chart and #5 on the US Billboard Hot 100. The album, which had received considerable critical acclaim, was re-released with two additional tracks and re-entered the UK Albums Chart at no.1 and made the Top 20 of the US Billboard 200. It was certified Gold in both the UK and the US and received two Grammy nominations. "Rhythm of Life" was actually released as a single four times in the UK (twice in 1990, and again in 1991 as a double A-side with the track "You've Got To Give Me Room"). Each time, it missed the Top 40 until a remix of the track was released in late 1995 which peaked at no.38.

An expanded double CD reissue was released in 2018 via Caroline International.
