The 2018 Tathra bushfire was a bushfire that burned between 18 and 19 March 2018 and primarily affected parts of the South Coast region in the Australian state of New South Wales. The fire, understood to have been caused by a failure in electrical infrastructure, began in the locality of Reedy Swamp, near Tarraganda, which spread east towards Tathra in the municipality of the Bega Valley Shire.
