CHIJ Saint Theresa's Convent is a government-aided Catholic girls' secondary school in Bukit Merah, Singapore.

It began by running Parish classes of the Church of St. Theresa, taught by sisters of the Holy Infant Jesus Congregation.

It grew to be an integrated school offering teaching in English and Tamil for primary-level students, who generally went on to the "Town Convent" CHIJ at Victoria Street (now CHIJ Toa Payoh) after leaving the school.

They are: Hockey, Netball, Bowling, Tennis, Softball, Floorball, Track and Field, Angklung, Choir, Dance and Movement, Band, Guitar, Drama, Debates, National Police Cadet Corps, Girl Guides, IJ Youth Mission, Entrepreneurship Club and Infocomm Club.

CHIJ St Theresa's Convent's niche is Hockey, which the team has won many awards and competitions throughout the recent years.

These six team houses form the basis of competition at the school's annual Sports Carnival.

During formal events, students representing the school wear the formal councillor uniform consisting of a long-sleeved white blouse, white skirt, with a navy blue blazer with the school crest on the left chest, along with a navy blue tie, a pair of black court shoes.

In 2013, Anne Kingsley-Lee received the Inspiring Teacher of English Award from Indranee Rajah, Senior Minister of State for Education and Law, at a ceremony held at the National Museum of Singapore.
