Archbishop Williams High School is a co-educational Catholic school in Braintree, Massachusetts, United States. It was founded in 1949 by the Sisters of Charity of Nazareth. Archbishop Williams' school seal, originally that of the founding order of nuns, is the pelican, which was an early Christian symbol of Jesus. The school's motto is Caritas Christi Urget Nos, or "The Love of Christ Drives Us On." Blue and gold are the school's colors. In the fall of 2017, Archbishop Williams dedicated its newly renovated cafeteria, The Stephen J. McGrath '71 Student Center.
