The Final Cut was the last Pink Floyd album with Roger Waters as a full member.

It came out in 1983. Waters wrote all the lyrics and most of the music, and it’s basically a solo album in all but name. He left shortly after.

People sometimes say The Wall (1979) was his last, but he was still a full member through The Final Cut. That album is the dividing line—after that, the band continued without him, and Waters did his own thing.

If you’re looking for the last true collaboration between all four classic members, that’s The Wall. But the last album with Waters as a voting, contributing member? The Final Cut.
