A name formerly given to various fevers occuring in tropics; esp. to a form of furious delirium accompanied by fever, among sailors, which sometimes led the affected person to imagine the sea to be a green field, and to throw himself into it.

Calenture is the fourth studio album by Australian rock group The Triffids, it was released in November 1987 and saw them explore themes of insanity, deception and rootlessness—the title refers to a fever suffered by sailors during long hot voyages. It reached No. 32 on the Australian Kent Music Report Albums Chart. In November 1987, it reached No. 24 on the Swedish Albums Chart, in May 1988 it peaked at No. 25 on the New Zealand Albums Chart. The album spawned three singles, " Bury Me Deep in Love" (1987), " Trick of the Light" and " Holy Water" (both in 1988). The latter track was recorded with American producer Craig Leon.

In 2007 Calenture was re-released as a 2× CD with five bonus tracks on the first disc and twelve tracks on the second disc, mostly rehearsal or studio demos of the original album tracks. In February it appeared on the Belgium Albums Chart Top 60.
