Nightlife is the seventh studio album by English synth-pop duo Pet Shop Boys, released on 8 October 1999 by Parlophone.

The album incorporates a variety of musical influences, including hard trance on the Rollo-produced "For Your Own Good" and "Radiophonic"; dance-pop on "Closer to Heaven" and "I Don't Know What You Want but I Can't Give It Any More"; disco pastiche on "New York City Boy"; and country music on "You Only Tell Me You Love Me When You're Drunk".

This was supported by a series of outfits in dark, muted colours, the most deviant of which incorporated culottes,[15] inspired by the attire of samurai,[14] instead of trousers.

It was visually influenced by the films THX 1138 (1971) in the initial transformation sequence (copying many of its shots and props precisely); Ridicule (1996), in the ritualistic dressing-up scene; 2001: A Space Odyssey (1968), in the decor of the living room with an illuminated floor; and A Clockwork Orange (1971), in the outdoor urban setting.
