Westgate is a rapidly developing regional town centre in the northwest of West Auckland in Auckland, New Zealand. The name of the suburb in which it is located was changed from "Massey North" to "Westgate" in 2013. The area was part of Waitakere City from 1989 to 2010 and its transformation and development are now priorities for Auckland Council.

The new regional town centre being built will be the hub for retail and commercial activity in the north west. The council has a number of development partners and will itself create the centre's new civic heart including a new library - Te Manawa located south-west to Te Pumanawa Square. NorthWest Shopping Centre located north-east to Te Pumanawa Square opened on 1 October 2015. As a part of NorthWest Stage 2 development, restaurants, retailers and offices around Te Pumanawa Square have gradually opened their doors since October 2016. The town square will feature areas for outdoor dining and the large civic space will be pedestrian friendly. A high quality and extensive network of parks and walkways will also be created.

Linking to Westgate's rapid commercial development, a Costco Wholesale warehouse club opened on 28 September 2022: the first in New Zealand.
