Bintan Regency (originally the Riau Islands Regency; Indonesian: Kabupaten Kepulauan Riau) is an administrative area in the Riau Islands Province of Indonesia. Bintan Regency includes all of Bintan Island (except for the city of Tanjung Pinang which is separately administered as an autonomous area of the island) and also includes many outlying islands including the Tambelan Archipelago and Badas Islands situated between Bintan and West Kalimantan; altogether there are 273 islands comprising the regency.

The Bintan Regency originally included all of the areas now comprising the Riau Islands Province, but on 4 October 1999 parts of the regency were split off to create separate Regencies of Karimun and Natuna (the latter originally including what in 2008 became the Anambas Islands Regency), together with the independent city of Batam. On 21 June 2001 the town of Tanjung Pinang on Bintan Island was also split off to become an independent city. In 2002 all these areas which had comprised the original Bintan Regency were brought together in a new Riau Islands Province when that was created from the archipelagic part of Riau Province. On 18 December 2003 a further regency – for the Lingga Islands – was created from part of the residual Bintan Regency.

Bintan Regency now covers an area of 2,045.32 km. It had a population of 142,300 at the 2010 census and 159,518 at the 2020 census; the official estimate as at mid 2023 was 175,873.

The island is located 40 kilometres from Singapore, with an area of 1,462.77 km, and it has a population of around 330,000 at the 2010 census (including Tanjung Pinang), which by the 2020 census had risen to 387,181, while the official estimate as of mid 2023 was 400,700. These population figures include the entire Bintan Island as well as outlying islands and archipelagoes that are included within Bintan Regency and Tanjung Pinang City. Famous places in Bintan Regency include Trikora Beach, on the east coast, and the international Bintan Resorts.
