Gilroy Catholic College is a Roman Catholic comprehensive co-educational secondary day school, located in Castle Hill, in the Hills District of Sydney, New South Wales, Australia. The College provides a Catholic and general education for students from Year 7 through to Year 12; it is administered by the Catholic Education Office of the Diocese of Parramatta.

Gilroy Catholic College was founded in 1980 and was built on the land formerly belonging to St Gabriel's School for the Hearing Impaired, thus making use of existing buildings.^[2] The school was originally intended for students from Year 7 to Year 10, but extended to years 11 and 12 in 1982.^[2]

Gilroy Catholic College was named after Cardinal Sir Norman Thomas Gilroy, the first cardinal born in Australia. As well as adopting his name, the college also made Cardinal Gilroy's personal motto, "Christ is my light", its official motto.^[2]

On 9 February 2008, The Sydney Morning Herald reported that, according to Green Party analysis of government figures, Gilroy received $12.2 million more in federal government funding than its entitlement under the socioeconomic status (SES) formula.^[3]
