The Division of Parramatta is an Australian Electoral Division in New South Wales. The division was created in 1900 for the first federal election in 1901. It is named for the locality of Parramatta. The name Parramatta is an Aboriginal word for "the place where the eels lie down".
The division is in the western suburbs of Sydney. It includes Constitution Hill, Dundas Valley, Granville, Harris Park, Holroyd, Mays Hill, North Parramatta, Oatlands, Old Toongabbie, Parramatta, Rosehill, Rydalmere, Telopea, Wentworthville, Westmead and parts of Dundas, Ermington, Guildford, Merrylands, Merrylands West, Northmead, North Rocks, Pendle Hill, South Granville and South Wentworthville.
The division lies between Labor voting areas of western Sydney and the Liberal areas on the North Shore. Because of this, any change to the boundary can change the political balance in the seat. For example, in the 2006 boundary change, Parramatta shifted from marginally Labor to marginally Liberal (as defined by the Australian Electoral Commission). Nevertheless, as was expected Julie Owens held the seat for the ALP with an increased majority.
