Triangle (published as ⊿)^[1] is the second studio album by Japanese girl group Perfume. It was released on July 8, 2009, through Tokuma Japan. Triangle builds upon the breakthrough success of their previous album Game (2008), with Yasutaka Nakata returning as executive producer.

Primarily an electropop record, Triangle takes influence from 1980s and 1990s music, with traces of disco and house. Its lyrical themes revolve around love and courage, particularly from a woman's perspective. Triangle received generally positive reviews from critics, who praised Perfume and Nakata on expanding their sonic identity, though some criticized its vocal processing.

It was preceded by the singles "Love the World", "Dream Fighter", and "One Room Disco", with the former becoming their first number one on the Oricon chart. Triangle itself was a commercial success, becoming their second chart-topping album and receiving a platinum certification from the RIAJ.^[2] Perfume embarked on their second nationwide tour shortly after its release.
