Shakespear Regional Park is a nature park in the Auckland Region of New Zealand. It is located at the tip of the Whangaparaoa Peninsula, and is named after the Shakespear family which bought the land in the 1880s from local Maori.

The Park is home to three walkways, Heritage Trail, Lookout Track and Tiri Tiri Track. Much of the coastline is lined by sandstone cliffs, which shelter the beach-lined Te Haruhi Bay. At the Park’s western border, a narrow lowland separates Okoromai and Army Bays.

Together with New Zealand Defence Force land to the north, most of the Park lies within the Shakespear Open Sanctuary. A 1.7-kilometre (1.1 mi) pest/predator-proof fence (completed March 2011) across the peninsula between protects the park’s wildlife. This includes resident invertebrates and lizards, along with birds migrating from the nearby Tiritiri Matangi island sanctuary. Brodifacoum poison airdrops were conducted in July 2011 to eradicate mammalian pests. The Shakespear Open Sanctuary Society has worked with the government landowners to establish and develop the sanctuary.
