Museu Histórico do Tocantins, Historical museum in Palmas, Brazil.

The Museu Histórico do Tocantins occupies the Palacinho, a wooden building erected in 1989 as the first construction in Palmas. It stands on the site of the former seat of the state government and houses the state's main collection of artistic, historical, archaeological and ethnographic objects.

The wooden Palacinho was built in 1989 as the first construction in Palmas and housed the Tocantins state government from 1 January 1990 to 9 March 1991, before the Palácio Araguaia was finished. It was listed by state law no. 431 on 28 July 1992 and became the Museu Histórico do Tocantins on 18 March 2002. Between January 2009 and March 2010 IPHAN restored the building, its annexes and the grounds.

The collection features crafts and daily objects from the Karajá and Xambioá peoples who have inhabited this region for centuries. Visitors can see how these communities shaped their way of life through the artifacts displayed.

The museum occupies the Palacinho, the first building erected in Palmas, in 1989, a raised wooden structure reached by steps. It was restored by IPHAN between January 2009 and March 2010, work that covered the building, the attached Capela de Santa Rita de Cássia and the outside area. The museum is run by the Fundação Cultural do Estado.

The museum displays the Governor's original office with authentic furnishings alongside an early state vehicle from 1989. This preserved Opala sedan provides insight into the practical conditions of the government's earliest years.
