The Taymyr Gulf (Russian: Таймырская губа, romanized: Taymyrskaya guba; also known as Taymyr Bay, Russian: Таймырский залив, romanized: Taymyrsky zaliv) is a gulf in the Kara Sea that includes the estuary of the Lower Taymyra.

The climate in the desolate area of the Taymyr Gulf is severe, with long and bitter winters and frequent blizzards and gales.

The Taymyr Gulf and its islands were explored by Alexander von Middendorff during his expedition to Siberia (1842–1845).

Bera Island was the farthest northern point he reached after exploring the Taymyr River from the south towards its estuary in August 1843.
