St. Mary's Academy of Caloocan City, also referred to by its acronym SMACC, is a private Catholic, coeducational basic education institution owned and administered by the Sisters of the Religious of the Virgin Mary (RVM) in Grace Park, Caloocan, Metro Manila, Philippines.

SMACC is located at Madre Ignacia Avenue (12th Ave.), Grace Park, Caloocan.

In response to the challenge to offer quality education, the school decided to pursue PAASCU accreditation.

Established initially as an all-girls school, the then Our Lady of Grace Academy, along with its neighboring all-boys school, Notre Dame of Greater Manila opened its doors to coeducation in 1999.

The Grade School was renamed the Lower Basic Education Department (LBED) and the High School, Upper Basic Education Department (UBED).
