St. Mary's High School is a private Catholic high school in Lynn, Massachusetts, United States. It is located in the Roman Catholic Archdiocese of Boston.
St. Mary's High School was established in 1881 as Saint Mary's Boys High School. A Girl's High School was added later, followed by coeducation. In 1989 the school began a junior high school starting with a 7th grade class only, with an 8th grade class added the following year. The junior high school added a 6th grade class in 2011 after Massachusetts moved to a middle school education model. Beginning in the 2023 school year they added an elementary and early education division to the school. St. Mary's Lynn now serves students from Pre-K - 12.
St. Mary's incorporated in 2006 as a private school, independent from the Archdiocese of Boston, and instituted a new governance structure with a head of school, principal, and twenty-member Board of Trustees, thus ending its period as a parochial school.
St. Mary's teams include:
The St. Mary's Girls Ice Hockey team went a perfect 25âÂÂ0 in 2007-2008 season. The girls then repeated this feat plus one to go 26âÂÂ0 in the 2008-2009 season. In addition, they went through the 2009-2010 season undefeated with one tie. The result: 100 consecutive games without a loss over three years before a loss to Hingham in the state semi-finals, and three Massachusetts Division 1 State Titles.
The former Girls High School building was demolished in 2005 to make way for the state-of-the-art William F. Connell Center, which provides a library, technology center, chapel, and classrooms.
Students are encouraged to participate in Christian service activities, such as Rachel's Challenge, Sant' Edigio, and assisting at My Brother's Table, a local food pantry.
