Restrepo is a 2010 documentary film about the Afghanistan war, directed by American journalist Sebastian Junger and British/American photojournalist Tim Hetherington.

The film explores the year that Junger and Hetherington spent in Afghanistan on assignment for Vanity Fair, embedded with the Second Platoon, B Company, 2nd Battalion, 503rd Infantry Regiment (airborne), 173rd Airborne Brigade Combat Team of the U.S. Army in the Korengal Valley. The 2nd Platoon is depicted defending an Observation Post (OP) named OP Restrepo, for PFC Juan Sebastián Restrepo, a Colombian-born naturalized U.S. citizen platoon medic who was killed earlier in the campaign.

The film follows the 2nd Platoon of Battle Company on a 15-month deployment in the Korengal Valley of northeast Afghanistan in the Nuristan area. The Korengal flows north to the Pech, which then flows east to the Kunar River valley on the border with Pakistan. The film chronicles the lives of the men from their deployment to the time of their return home. The Korengal Valley was at the time regarded as "the deadliest place on Earth" (as stated in the documentary itself, trailers, and television commercials on the National Geographic Channel). The goal of the deployment was to clear the Korengal Valley of insurgency and gain the trust of the local populace.
