Dogiyai Regency is one of the regencies (kabupaten) in the Indonesian province of Central Papua. The Regency was created on 4 January 2008 from what had previously been the southern districts of Nabire Regency. It covers an area of 7,052.92 km<sup>2</sup> (revised from 4,237.4 km<sup>2</sup>), and had a population of 84,230 at the 2010 Census and 116,206 at the 2020 Census; the official estimate as at mid 2024 was 125,178, comprising 64,996 males and 60,182 females. The regency seat is the town of Kigamani (in Dogiyai District).
During the 2020s, Dogiyai was involved in a border dispute with neighboring Mimika and Deiyai regencies, resulting in the Kapiraya conflict.
When it was formed in January 2008, the new Dogiyai Regency comprised three districts (distrik) from within the southern part of the existing Nabire Regency, but these were subsequently reconstructed into the present ten districts. The former Sukikai District was divided between new Sukikai Selatan (in the south) and Piyaiye (in the north) Districts. The Mapia District was also divided, with the southern half split between new Mapia Barat and Mapia Tengah Districts, leaving a residual Mapia District in the north. The Dogiyai (in the west), Kamu Selatan, Kamu Timur and Kamu Utara Districts were formed from most parts of the Kamu District.
The following is a table of the current districts (kecamatan) - and of the 79 villages (all rated as rural kampung) by district - within the Dogiyai Regency, based on Statistics Indonesia, with the district areas and their populations at the Censuses of 2010 and 2020, together with the official estimates as at mid 2021.
