Opalescent is the debut studio album by English musician and producer Jon Hopkins, released on 30 June 2001 under Just Music and absolute zero.

Kevin Lozano from Pitchfork gave Opalescent a 5.6/10 and wrote: "This reissue of the electronic composer’s first album, made in his early 20s, rings thin and hollow compared to the dark genius of his later work.

"[9] Angus McKeon from Clash gave Opalescent a 7/10 and wrote: "When compared to some of his later projects, you can recognise signs of inexperience in Hopkins production.

Using synth oozes, phased and echoed guitars and pianos and chilled beats, his wonderful tunes drift from calm to eerie power like a restless sea.

DJ Magazine gave it 4/5 stars, and stated "Piano, guitar strings and slow beats blend like the clouds at sunset (or an opiate smoothy) filtering in and out like elegantly wasted beauty.
