Until the 1990s, Insein, about 20 miles (32 km) from central Yangon, was beyond Yangon's city limits although by the 1980s, Insein was already integrated with the rest of the city. With the expansion of Yangon's city limits in the 1990s which also included founding new satellite towns, Insein was formally incorporated into Yangon.

The word "Insein" means "precious lake" in the Burmese language, and is also a former name of Inya lake. However, the etymology of "Insein" is derived from the Mon language term Mon: အၚ်စိၚ် (/ɛŋ coiŋ/), meaning "elephant lake."
