Banyumas (Javanese: ꦧꦚꦸꦩꦱ꧀, formerly spelled "Banjoemas") Regency is an inland regency (Indonesian: kabupaten) in the southwestern part of Central Java province in Indonesia. Its capital is the town of Purwokerto, but that town no longer has a central administration and is split over four of the districts within the Regency, with a combined area of 41.65 km and a population of 236,162 as of mid-2024. The Regency covers an area of 1,391.15 km, and had a population of 1,554,527 at the 2010 Census and 1,776,918 at the 2020 Census; the official estimate of the population as of mid-2024 was 1,847,097 (comprising 928,905 males and 918,192 females).
The term Banyumasan is also used as an adjective referring to the culture, language, and peoples of the wider Banyumas area, equivalent to the pre-independence Banyumas Residency. The language of Banyumasan is of Austronesian origin and is usually considered to be a dialect of Javanese.
