The Geelong College is an Australian independent and co-educational, Christian day and boarding school located in Newtown, an inner-western suburb of Geelong, Victoria.

Established in 1861 by Alexander James Campbell, a Presbyterian minister, the Geelong College was formerly a school of the Presbyterian Church of Australia and is now operated in association with the Uniting Church in Australia but is not governed or managed by the church. The school has a non-selective enrolment policy and currently caters for over 1,200 students from kindergarten to Year 12, including around 100 boarding students from Years 7 to 12. The boarding students are accommodated in two boarding houses at the senior school campus: Mackie House for boys, Mossgiel House for girls.

The college is affiliated with the Headmasters' and Headmistresses' Conference, the Association of Heads of Independent Schools of Australia, the Junior School Heads Association of Australia, the Association of Independent Schools of Victoria, the Australian Boarding Schools Association, and has been a member of the Associated Public Schools of Victoria since 1908.

Following the closure of the first Geelong Grammar, Campbell established a committee to found a new Presbyterian school. On 8 July 1861, Geelong College was officially established. The school year later started with an enrolment of 62. George Morrison was appointed the first principal and three years later became the owner of the school. The school moved to its present location in 1871. The architects Alexander Davidson and George Henderson designed its main building.

In 1908, the college returned to the ownership of the Presbyterian Church of Australia and became a member of the Associated Public Schools of Victoria (APS). St David's Presbyterian Church at the corner of Talbot St and Aphrasia St, Newtown is currently used by the School for religious services. Traditionally, the school used St George’s Presbyterian Church on Latrobe Terrace for Presbyterian Services. Anglican services, when required, were provided at All Saints Church on Noble St. Presbyterian Services however, were transferred to St David’s Church in 1962. The Geelong College Chapel was dedicated on 8 March 1989 as the centre of the school's spiritual life. It was formerly the school’s House of Music, designed by Philip Hudson, built c. 1936 and opened in 1937.

Land was acquired in 1946 for a new preparatory campus which did not open until 1960. This particular campus became co-educational in 1974, with co-education being extended to the senior campus in 1975. The college undertook an extensive redevelopment and refurbishment of the middle school, which is on the preparatory campus, in 2012. In 2015 Principal Andrew Barr resigned after he was photographed watching pornography in his office.

At the middle school, there are four houses: Pegasus (white), Bellerophon (blue), Minerva (red) and Helicon (green), which meet for sporting events throughout each year. The house model is not used for pastoral care at this campus. The names of these houses originate from Roman mythology.

Geelong College offers its senior students the Victorian Certificate of Education (VCE).
