Triactis is a genus of sea anemone in the family Aliciidae. It is monotypic, having only one species – Triactis producta. This species is found in shallow waters in the Indo-Pacific where it lives on the seabed, rocks and corals. It derives much of its energy needs from the symbiotic algae it contains. It also forms a mutualistic relationship with small Lybia crabs.
