Breid Bay is a bay about 20nmi wide, irregularly indenting, for as much as 12nmi, the ice shelf fringing the coast of Queen Maud Land. This feature was charted and descriptively named "Breidvika" ("broad bay") by H.E. Hansen, as a result of aerial photographs made on February 6, 1937, by the Lars Christensen Expedition of 1936–37.
