LaSalle Catholic College is an independent Roman Catholic comprehensive co-educational secondary day school, located in Bankstown, a south-western suburb of Sydney, New South Wales, Australia. The De La Salle Brothers run the college in the tradition of Saint John Baptist de La Salle.

The college provides a Catholic and general education for students from Year 7 to Year 12, with oversight provided by the Sydney Catholic Schools of the Archdiocese of Sydney.

LaSalle Catholic College was formed in 1999. It is an amalgamation of three previous schools that existed on the site – De La Salle College (7–10) (1951–1998), Benilde High School (11–12) (1968–1999), and Nazareth Senior Girls College (11–12). Both Benilde and De La Salle were run by the De La Salle Brothers whilst Nazareth College was run by the Josephite sisters in the tradition of Blessed Mary McKillop. There are no longer Josephite sisters at the college, but several De La Salle Brothers still work at the College and live in the nearby Brothers' Residence.

In 2016, LaSalle Catholic College transitioned from single-sex (boys only) to co-educational with facilities upgraded to accommodate this change.

LaSalle Catholic College is located on a single campus in Bankstown. The college is located near the Hume Highway and occupies a fairly large site which forms part of the Catholic Parish of Saint Felix, Bankstown. The College has expanded significantly since 1999, with new facilities built as well as upgrading of existing ones.

The Saint Yon Trade Training Centre, which delivers vocational training to students was opened in 2013, at a cost of $7 million. The training facility is shared with a number of Catholic schools in Sydney.

The LaSalle 'Heart Building' project, which commenced in 2019, saw the development of a new multi-purpose complex with pedestrian links to neighbouring buildings. The multi-purpose complex delivered under the project includes an expanded gymnasium, a 200-seat lecture theatre, a dance studio and a VET healthcare room. The project was completed in April 2021, at a cost of $11.3 million.
