Joshua "Josh" Washington is one of the eight main protagonists and a playable character in Until Dawn. He is the older brother of Hannah and Beth Washington. After a prank caused the disappearance of his twin sisters, he invites his friends back to his family lodge a year later in an attempt to forget the tragedy. Unbeknownst to the group however, Josh planned a night of terror to exact revenge.

Josh is the first child of movie mogul Bob Washington and his wife, Melinda. He, along with his family, would frequently travel to the family lodge located on Blackwood Mountain during each summer and winter. As he got older, his father became too busy to hang out with him, which brought him and his sisters closer together.

Josh was studying psychology at college prior to Hannah's and Beth's disappearance, which caused him to drop out. He has struggled to come to terms with the disappearance of his sisters.

A bit older than the rest of the group, Josh is something of an older brother figure to Chris. He loves taking the helm, organizing cool events, and making sure that everybody has an awesome time.

Josh definitely has a bit of a party-animal streak (honed in his freshman year), but his warm and friendly personality will win everybody around in the end.
