Nebeska vrata (engleski: Heaven's Gate) je bio naziv za NLO religiju koju su vodili Marshall Applewhite i Bonnie Nettles.

Kraj kulta je koincidirao s dolaskom komete Hale-Bopp godine 1997. Applewhite je uvjerio 38 svojih pristaša da izvrše samoubojstvo kako bi se njihove duše mogle ukrcati na svemirski brod za koga su vjerovale da se krije iza komete koja je nosila Isusa; takva vjerovanja su neke promatrače natjerala da grupi daju karakteristike "NLO religije."
