St Aloysius College is a Catholic, day school for girls, situated in Adelaide, South Australia. St Aloysius College, also known as "SAC", was established by the Sisters of Mercy in 1880, and educates over 950 students from Reception to Year 12. The school is home to the SA Adelaide Language Centre, established in 1994 and accredited by English Australia for English language tuition. Twenty-four Irish Sisters of Mercy left Argentina for Australia in 1880 due to political unrest. They purchased a private home belonging to George Dutton Green in Angas Street, establishing a convent and school. The school was named St Angela's but renamed St Aloysius in 1901. The school has been extended over time and convent buildings were extended in 1920, including the building of a chapel. The Sisters of Mercy closed the convent in 2005 and the school took over all of the buildings on the site. SAC has a Social Justice group for the students and this group leads the school community on social justice issues. During the school year, SAC organises fundraising activities, in particular, the school walkathon, "Mercy Day" and "The Can Drive".
