Teluk Wondama Regency or Wondama Bay Regency (Indonesian: Kabupaten Teluk Wondama; Dutch: Regentschap Wondammen-baai) is a regency of West Papua province of Indonesia. It covers a land area of 4,844.035 km, and had a population of 26,321 at the 2010 Census and 41,644 at the 2020 Census; the official estimate as at mid 2023 was 44,534 (comprising 23,395 males and 21,139 females). The administrative centre lies in the small town of Rasiei.

The northern half of the Regency contains several coastal districts along the east coast of the Bird's Head Peninsula and Bomberai Peninsula, and across Wondama Bay (a deep inlet to the south of Cenderawasih Bay) on the west coast of the Wondiboy Peninsula, but it also includes a number of islands in the southwest part of Cenderawasih Bay. The southern half of the Regency comprises the large but landlocked and nearly uninhabited Naikere District.

Geographically, the district is located between 132°35' - 134°45' East Longitude and 0°15' - 3°25' South Latitude.

Most of the islands in Wondama Bay Regency are surrounded by coral reef that is teeming with rich marine life. Rasiei, the administrative capital of Wondama Bay, is a small port located on the east coast of Wondama Bay at the foot of the Wandammen or Wondiboy Peninsula which is covered by pristine tropical rainforest. The largest town is actually Wasior, further north along that coast. The coral reef and tropical rainforest have become important tourist attractions in this regency. The Department of Tourism and Culture of Wondama Bay Regency, in cooperation with the Indonesian Tourist Guide Association, has launched a website called Wondama Tourism to attract visitors to the regency.

Most of the Wandamen or Wondiwoi Peninsula is covered by the Wondiwoi Mountains (Pegunungan Wondiwoi) National Reserve, while most of the islands in the north of the regency (together with Anggrameos Island which lies off the east coast of the Peninsula and is part of Central Papua Province) are included in the Cenderawasih Bay National Park (formerly described as a Marine Nature Reserve until re-designated in 2002).

The regency comprises thirteen districts (distrik), tabulated below with their populations at the 2010 Census and the 2020 Census, together with the official estimates as at mid 2023. The table also includes the locations of the district administrative centres, the number of administrative villages in each district (totaling 75 rural kampung and one urban kelurahan - the latter being Wasior I), and its post code.
