Anibal Cambas Regional Museum, Regional history museum in Posadas, Argentina.

The Aníbal Cambas Regional Museum stands at Roque González 550 in Posadas's Parque Paraguayo. Its present building, a chalet inaugurated on 25 May 1947, replaced the original structure of 1940, which had one large central hall flanked by two side rooms. Inside are exhibition rooms, an auditorium for 150 people, a library and a newspaper archive.

The museum was inaugurated on 20 March 1940 under the Junta de Estudios Históricos de Misiones, with Aníbal Cambas as its first president; the municipality had lent the board land in Parque Paraguayo. In 1947 one hall was ceded to the Cuerpo de Zapadores Pontoneros of the Argentine Army, so a new building was erected facing the park and opened on 25 May 1947. Cambas, born in Posadas on 18 May 1905 and died on 21 October 1982, was a public notary, musician and poet.

The rooms are named after Julio César Sánchez Ratti, Félix de Azara and Federico C. Maynthuzen, while the library honours Clotilde González de Fernández Ramos. Collections cover the altoparanaense, umbú, eldoradense, tupí-guaraní, guayakí and jesuítico-guaraní cultures, plus a mataco-guayakí collection and a newspaper archive.

The museum stands at Roque González 550 inside Parque Paraguayo, in front of the park. Its exhibition rooms and a 150-seat auditorium share the building with the Junta de Estudios Históricos de Misiones. A library and newspaper archive (hemeroteca) are also on site for research visits.
