Actinoporus elegans, commonly known as the Elegant Anemone or the Brown-striped Anemone, is a species of sea anemone in the family Aurelianidae. This species may exhibit a high degree of colour variability, from blue to white to nearly transparent. A. elegans inhabits the tropical Atlantic Ocean, from the Caribbean Sea to Brazil. Although previously known only from the western Atlantic, populations were discovered in the east Atlantic at São Tomé and Príncipe in 2004 and in 2006, the first records of this species in the area.
