USS Blue (DD-387) was a Bagley-class destroyer of the United States Navy. J. Wright was her captain from 14 August 1937.
On 7 December 1941, during the attack on Pearl Harbor, Blue was in the harbor. She was still afloat when the attack ended.
On 9 August 1942 she was at the Battle of Savo Island. She was on radar picket southwest of Savo Island, on the southern side of the island. Mikawa's column passed very near her. The ships went by unseen, and Blue did not sight them.
In the morning she helped take Canberra's crew off. Blue was still afloat when the battle ended and was not sunk in it.
