A teen was robbed at knifepoint on an Upper West Side subway train early Wednesday, authorities said.

The 17-year-old boy was on a southbound 1 train near the West 79th Street station when the thief threatened him with a knife around 2:40 a.m.

During the incident, the robber told the victim to “give me your stuff” and to “take off your shoes,” according to police.

The teen did as he was told and turned over his sneakers, backpack and cellphone.

He was not harmed during the robbery.
