Giant's Tank Sanctuary (Tamil: கட்டுக்கரை குளம் சரணாலயம் Kaṭṭukkarai Kuḷam Caraṇālayam) is a wildlife sanctuary in northern Sri Lanka, approximately 200NaN0 south east of Mannar.
Giant's Tank and its surrounding area was designated as a sanctuary on 24 September 1954 under the Fauna and Flora Protection Ordinance (No. 2) of 1937.[1] [2] It had an area of 3941ha in 1990.[1] It currently has an area of 4330.1ha.[2]
