Analogue Bubblebath was the first EP released by techno and IDM artist Richard D. James, under his commonly known alias, AFX. It is also the first release in the Analogue Bubblebath series. It was his first release under this alias. Tom Middleton collaborated on the two concluding tracks.

The EP consists of four songs, all done in the acid house techno style which was popular at the time. It was released in 1991 on TVT Records and Mighty Force Records in both CD and 12" vinyl formats.

Analogue Bubblebath, both the song and the EP, are occasionally referred to as "Analogue Bubblebath 1". The first two tracks (with "Isopropophlex" appearing in a longer form titled "Isoprophlex") can be found on the R&S Records compilation Classics.
