Thonze (Burmese: သုံးဆယ်, also spelt Thonse) is a town in Tharrawaddy Township in western Bago Region, Myanmar.

[1] During British colonial rule, Thonze was a logging hub where the taungya variety of teak was first grown in plantation style.

[3] The missionary Marilla Baker Ingalls settled in Thonze in 1859, describing it as a remote village, requiring a two-day boat trip from Rangoon up the Hlaing River.

She set up a mission and created a community of Baptists through her life in the village.

[4] The first rail line to Thonze was built in 1877, and the village grew into a station town.
