Alien 4 is the twentieth studio album by the English space rock group Hawkwind, released in 1995.

At the end of 1994, with the group established as a three piece of guitarist Dave Brock, bassist Alan Davey and drummer Richard Chadwick, they felt they were lacking visually in terms of showmanship.

In addition, guitarist Jerry Richards, another musician involved in the English free-festival scene as a member of the group Tubilah Dog, started contributing to some live dates and recording sessions.

This new line-up undertook a 13 date North America tour in April 1995, then recorded a BBC Radio 1 session on 27 July, at Maida Vale Studios.

The album was recorded at Rockfield Studios in the summer, and the Area S4 EP featuring a "Roswell Mix" of "Alien (I Am)" was issued.
