Tiakur is a kelurahan and the regency seat of Southwest Maluku Regency in Maluku, Indonesia. The town was purposefully established as the capital of the regency following its creation in 2008. It serves as the administrative center for the region despite being smaller than Wonreli on Kisar Island, which is noted as a larger and more developed town within the regency.
The designation of Tiakur as the capital resulted from a political debate during the initial formation of the Southwest Maluku Regency. As of 2022, the population of the town is approximately 4,227 people, with most of the settlement located within the boundaries of the Tiakur kelurahan.
