The 2013 NBA Development League expansion draft was the sixth expansion draft of the National Basketball Association Development League (D-League). The draft was held on August 29, 2013, so that the newly founded Delaware 87ers could acquire players for the upcoming 2013–14 season. The 16 players were chosen from a pool of unprotected players among the league's teams. Each returning D-League team could protect up to 12 of their players from being selected.

Two of the players that the Legends chose had previously been named NBA D-League All-Stars: Leo Lyons and Sean Williams. A Boston College alumnus, Williams was also one of two players taken who had previously been selected in an NBA draft (Darington Hobson was the other).
