The area now known as Ellis Lane was originally home to the Gandangara people of the Southern Highlands although the Muringong, southernmost of the Darug people, were also known to inhabit the area. In 1805, wool pioneer John Macarthur was granted 5,000 acres (20 km²) at Cowpastures (now Camden). Ellis Lane is still primarily a rural locality.

Ellis Lane lies in the south ward of Camden Council, currently represented by Chris Patterson (who is also the Mayor of Camden), Eva Campbell and Fred Whiteman. It sits within the state electorate of Camden, represented by Labor's Geoff Corrigan, the former Mayor of Camden, and the federal electorate of Macarthur, represented by Liberal's Pat Farmer, the former ultra-marathon runner. Centennial Lane is a street off Ellis Lane and is a part of the Ellis Lane Suburb
