Corstorphine is a suburb of southwest Dunedin in the South Island of New Zealand.

Corstorphine is a largely residential suburb, containing a substantial amount of state housing built from the 1930s to the 1960s.

The name "Corstorphine" comes from the house and land owned by early settler John Sidey, who arrived in Dunedin in 1848.

Sidey's son Sir Thomas became a prominent local and national politician during the later nineteenth century.

Here, Easther Crescent — named after the area's first house owner, a naval captain — runs along a terrace at the edge of the hill, connecting with Saint Clair at Allandale Road to the south and descending to Forbury Corner and Caversham in the northeast.

[6] Built on part of Sidey's former farmland, the suburb was always intended to be residential,[7] and has no commercial premises.
