Assumption College Sriracha (ACS) is a private, Catholic-run school on the Eastern Seaboard of Thailand, in Si Racha District, Chonburi Province.

The campus covers 120 acres (0.49 km2), and has play spaces, football pitches, a swimming pool, and a sports stadium.

Former Thai prime ministers and other leading figures have been educated at Assumption colleges and universities.

[citation needed] Assumption College Sriracha runs several English-language programmes and employs native-speaking English teachers.

After the war, Assumption College reopened in Bangkok, but hostels for students were damaged and so some pupils remained in Sriracha.
