The Division of Parramatta is an Australian electoral division in the state of New South Wales. The division was created in 1900 and was one of the original 65 divisions contested at the first federal election. It is named for the locality of Parramatta. The name Parramatta has been sourced to an Aboriginal word for the area. The Darug people had lived in the area for many generations, and regarded the area as a food bowl, rich in food from the river and forests. They called the area Baramada or Burramatta ("Parramatta") which means "the place where the eels lie down".
