Davidson is an electoral district of the Legislative Assembly in the Australian state of New South Wales.

Davidson includes portions of two of the most Liberal-supporting areas of Sydney, and has been in the hands of the Liberal Party for its entire existence.

However, even on those occasions, the Liberals won enough primary votes to retain the seat outright.

Since the 1990s, Labor has been lucky to get 30 percent of the two-party-preferred vote, and has even been pushed into third place on some occasions.

On its current boundaries, Davidson includes all of the namesake suburb of Davidson, as well as North Turramurra, St Ives, St Ives Chase, Killara, East Killara, Lindfield, East Lindfield, Roseville and Roseville Chase.
