Lisa Maria Singh is an Australian former politician. She was a Senator for Tasmania from 2011 to 2019. She had previously been a member of the Tasmanian House of Assembly, representing the division of Denison from 2006 to 2010. The granddaughter of an Indo-Fijian member of the Parliament of Fiji, Singh was Australia's first female federal parliamentarian of Indian descent.

Indo-Fijians, also known as Indian Fijians, are Fijian citizens of Indian descent, and include people who trace their ancestry to various regions of the Indian subcontinent. Although Indo-Fijians constituted a majority of Fiji's population from 1956 through the late 1980s, discrimination and the resulting brain drain resulted in them numbering 313,798 (37.6%) out of a total of 827,900 people living in Fiji as of 2007.
