Damien Gildea (b. 1969) is an Australian mountaineer and Antarctic explorer who climbed extensively in Antarctica, Nepal, Tibet, Pakistan, Bolivia, Alaska, New Zealand and elsewhere. His Antarctic ascents include Mount Vinson, Mount Shinn, Mount Craddock, Mount Gardner, Mount Bentley, Mount Anderson (first ascent) and several other peaks in Vinson Massif, Craddock Massif and northern Sentinel Range in 2001–2007, as well as Mount Friesland and Mount Bowles on Livingston Island in 2003. The high precision GPS data collected by his team was used in subsequent American and Bulgarian mapping.
In 2007 Gildea published the new 1:50,000 color topographical map Vinson Massif & The Sentinel Range including a number of new features named by the USGS.
In November 2010 published Gildea's new book Mountaineering In Antarctica: Climbing In The Frozen South.
