Bandar Baru Bangi (literal translation: Bangi New Town) is a township and satellite town of Kajang situated in Hulu Langat District, in southeastern Selangor, Malaysia.

It is named after the small town of Bangi situated further south. It is located between Kajang and Putrajaya (formerly Prang Besar) and is about 25 km away from the capital city, Kuala Lumpur. Bandar Baru Bangi acts as the satellite town and Central Business District of Kajang, with most banks and government offices operating out of the township. Bandar Baru Bangi is also known as "Bandar Berilmu" or knowledgeable city since 2008 as numerous universities are located here including the National University of Malaysia.

The name of the town usually is abbreviated as "BBB". As of 2016, there are 16 town sections in the town. While not an official town section, the new township Kajang 2 is the latest extension to Bandar Baru Bangi due to its close proximity to Seksyen 5.
