Wentworthville was an electoral district of the Legislative Assembly in the Australian state of New South Wales, first created in 1962. The seat was absorbed into surrounding electorates in a redistribution prior to the 1991 election and recreated in the redistribution prior to the 1999 election. At the 2003 election, Pam Allan won the seat with 54% of the first preference votes. This was a marginal improvement over the 1999 election. It was abolished again for the 2007 election, with the larger part of it going to the new electoral district of Toongabbie.
