Mount Saint Patrick College, also known as Mt Saint Patrick College, is an independent Roman Catholic co-educational secondary day school, located in Murwillumbah, New South Wales, Australia, operating within the system administered by the Lismore Catholic Education Office, a subsidiary of the Roman Catholic Diocese of Lismore.

Mt St Patrick caters to students in Year 7 to Year 12. It was opened in 1926 by the Presentation Sisters and was administered and staffed by them until 1989. It derives its name from St Patrick, the patron saint of Ireland, whose feast day is celebrated by both the college and local communities. In 1966, following the closure of other local Catholic secondary schools, the school became known as Mt St Patrick Regional High School, with 192 enrolled students. The appointment of the school's first lay Principal in 1990 ended 64 years of leadership by the Presentation Sisters, leading to the renaming of the school in 1998 to Mt St Patrick College. In 2011 the Australian Government's Economic Stimulus Package enabled the opening of the St Mary of the Cross Science and Language Centre. A record enrolment of 695 students was recorded in 2012. On 15 March 2013, the Gilbey Multipurpose Centre was officially opened, costing $6,230,256.

Students are divided into eight houses. Each house is named after a person or place significant to the college and its establishment.

House	Colour
Assisi	Aqua
Doyle	Pink
Ignatius	Orange
Lisieux	Red
Loreto	Blue
Lucan	Green
Nagle	Gold
Romero	Purple

The houses compete for the St Patrick's Champion House Trophy which is presented to the winning house on St Patrick's Day every year. The winning house is determined by the accumulated points each house receives through sporting and academic achievements of each of its students.
