Tha Sawang (Thai: ท่าสว่าง, in Thai pronounced as /tʰâː sā.wàːŋ/) is a subdistrict (tambon) of Mueang Surin District, Surin Province, northeastern Thailand.
Neighboring subdistricts are (from the north clockwise) Na Di, Kae Yai, Nok Mueang and Kho Kho of Mueang Surin, Surin Province and Nong Teng, Chumsaeng, and Lamduan of Krasang District, Buriram Province.
Agriculture is the main activity of the sub-district, with rice and vegetables as the main products. The second job of the people in the area is silk weaving. The brocade/silk from this sub-district was selected as the official souvenir of the APEC Summit 2003 in Bangkok.
