The Strand Fiord Formation is a Late Cretaceous volcanic component, located on northwestern and west-central Axel Heiberg Island, Nunavut, Canada. The formation contains flood basalts which are found on western Axel Heiberg Island at Dragon Cliffs 300 m (984 ft) tall.

The Strand Fiord Formation contains columnar jointing units that are usually 1 m (3 ft) to 3 m (10 ft) in diameter. The formation is interpreted to represent the cratonward extension of the Alpha Ridge, a volcanic ridge that was active during the formation of the Amerasian Basin.[2] The Strand Fiord Formation is also part of the High Arctic Large Igneous Province.
