Swimming competitions at the 2015 Southeast Asian Games was held at the OCBC Aquatic Centre in the Singapore Sports Hub in Kallang, Singapore from 6 to 11 June 2015. Built only a year earlier, the venue is hosting the Southeast Asian Games for the first time. It was used to host the second Southeast Asian Swimming Championships in 2014 as a test bed for the organisers, with the 2015 Southeast Asian Games volunteers hired to also volunteer in the 2014 Swimming Championships to help in the familiarisation of the new venue.
