Oatlands College () is a voluntary Christian Brothers secondary school for boys aged 12âÂÂ18, located in Mount Merrion, County Dublin in Ireland. It prepares students for Junior Certificate and Leaving Certificate examinations.
The Christian Brothers first established a community in 1951, before opening the school in 1955. It is now under the Trusteeship of the Edmund Rice Schools Trust. The school added a single storey extension in 1969 and later added a sports hall in 1980. After some modernisation in 1995, the school opened a new wing in 1999. In the summer of 2010, a new technology room, drawing room, music room, a second computer room, two new class rooms and two new science laboratories were added to the building. On 10 May 2012, a new sports hall with a canteen and a new classroom was opened by the President of Ireland Michael D. Higgins.
Sports undertaken at Oatlands include GAA, soccer, basketball, badminton, tennis, table tennis, cricket and athletics. The school has also a successful golf team who became the South Dublin champions in 2018, 2019 and 2020. In 2017, the senior badminton team won the South Dublin Cup. In 2018, the junior badminton won the South Dublin Cup with the seniors losing out to Benildus College.
School teams enter business quiz competitions, inter-school debate competitions, student enterprise awards, the Young Scientist and Technology Exhibition, Young Social Innovators and Edmund Rice Awards.
Each year, a college musical is performed by Transition Year students in association with the girls from Rockford Manor.
A school newsletter, 'Oatlands News', is published twice a year.
