State Highway 11 (SH 11) is a 30 kilometre stretch of highway in the North Island of New Zealand.

Its main destination is the Bay of Islands township of Paihia.

Until 2004, it terminated at Tohitapu Road, in southern Paihia township.

It then leaves Paihia to the west along Puketona Road and passes through Haruru, before terminating at Puketona Junction on SH 10, 10 km (6.2 mi) south of Kerikeri.

SH 11 provides access, via Paihia, to the Waitangi Treaty Grounds: the location where the Treaty of Waitangi was signed in 1840.
