Blackett Strait is a waterway in the Western Province of the Solomon Islands. It lies between the islands of Kolombangara to the north, and Arundel Island (Kohinggo) to the south. It connects Vella Gulf to the west with Kula Gulf to the east. It is almost certainly named after Lt. Frederick Arthur Blackett (1846-1880), the youngest son of Sir Edward Blackett 6th Bt., who served on HMS Thalia as part of the China Station from 1872 to 1873.[1]
