The Tobago House of Assembly (THA) is a unicameral devolved legislative body responsible for the island of Tobago within the unitary state of Trinidad and Tobago. The THA was re-established in 1980 to rectify some of the disparities in the relationship between the two islands, though a prior body using the same name existed from 1768 to 1874.
