Kupang Regency is a regency in East Nusa Tenggara province of Indonesia. It occupies the far western end of Timor Island (apart from the area of Kupang city, which has been administratively separated from the Regency since 11 April 1996), together with the smaller island of Semau (off the southwestern tip of Timor) and other minor offshore islands (of which Kera is the only inhabited). Other islands further to the southwest and west which were formerly part of Kupang Regency have been separated administratively - the Rote Islands Group on 10 April 2002 (to form Rote Ndao Regency), and the Savu Islands Group on 29 October 2008 (to form Sabu Raijua Regency). The residual regency covers an area of 5,668.26 km2. It had a population of 304,548 at the 2010 Census and 366,383 at the 2020 Census; the official estimate as at mid-2023 was 387,217. The capital of Kupang Regency is at Oelamasi.
