Gilbert Seamount is a large seamount in the Tasman Sea located 450 km (280 mi) west of the South Island of New Zealand at the southern edge of the Lord Howe Rise. It has an elongated northwest–southeast trend, covering an area of about 11,500 km2 (4,400 sq mi) and rising to 2,400 m (7,900 ft) below sea level.
The seamount is a continental fragment that rifted away from the South Tasman Rise and Challenger Plateau during the Cretaceous breakup of Gondwana. It is separated from the easterly Challenger Plateau by a 4,400 m (14,400 ft) deep saddle.
Gilbert Seamount has been known under a variety of names throughout its history, including Gilbert Ridge, Gilbert Seamount Complex and Joseph Gilbert Seamount.
