Kotamobagu is a landlocked city in North Sulawesi, Indonesia. Having previously been a town within the Bolaang Mongondow Regency, Kotamobagu was separated from that regency on 2 January 2007 to become an autonomous city. It is the principal centre of the southern part of the province, the Bolaang Mongondow region, which has been under consideration by the Indonesian government to be separated from the rest of North Sulawesi and formed into a separate province. The city covers an area of 108.89 km2,Badan Pusat Statistik, Jakarta, 27 February 2026, Kota Kotamobagu Dalam Angka 2026 (Katalog-BPS 1102001.7174) and had a population of 107,459 at the 2010 Census,Biro Pusat Statistik, Jakarta, 2011. rising to 123,722 at the 2020 Census;Badan Pusat Statistik, Jakarta, 2021. the official estimate as at mid 2025 was 121,756 (comprising 62,396 males and 59,360 females).Badan Pusat Statistik, Jakarta, 27 February 2026, Kota Kotamobagu Dalam Angka 2026 (Katalog-BPS 1102001.7174)
