The Biak paradise kingfisher (Tanysiptera riedelii) is a tree kingfisher that is endemic to the Indonesian island of Biak which is one of a small group of islands located in Cenderawasih Bay near the northern coast of Papua.

This bird has a turquoise-blue back with a white belly and tail streamers and a reddish beak.

The crown, nape and sides of the head as well as the upper parts are a bright glossy turquoise-blue.

The two central tail feathers are greatly elongated and have bare shafts which flare out at the tip into racket-like lobes.
