Nightlife is a collective term for entertainment that is available and generally more popular from the late evening into the early hours of the morning. It may include pubs, bars, nightclubs, parties, live music, concerts, cabarets, theatre, cinemas, shows, and some restaurants. These venues often require a cover charge for admission. Nightlife entertainment is often more adult-oriented than daytime entertainment. People who prefer to be active during the night-time are called night owls.

Nightlife is a human social activity.
