Barrytown (originally known as Seventeen Mile Beach and Fosbery) is a town in the West Coast region of New Zealand's South Island.

The land is originally Māori, and the local hapū is Ngāti Waewae of the iwi Ngāi Tahu.

Pakiroa Beach along the Barrytown Flats was an important food source for local Māori, and middens of tuatua shells attributed to the iwi Waitaha have been dated to 1500 AD.

[5] A gold rush in the 1860s led to workings at Seventeen Mile Beach and Canoe Creek, and by 1879 about 2000 miners were living in the area.

[7][8] The following year, however, a government opinion poll of residents and miners was held to choose between Fosbery and Barrytown.

[9] By 1895, Barrytown had a Catholic church, a state school, two lodging-houses (Luis's and Cargill's), a smithy, and the All Nations Hotel.

[12] Barrytown is a hub for arts and crafts, including stone carving and knife making.

[16] Built in 1929, the Barrytown Settlers Hall is a well-known music venue and has been hosting gigs since 1972. International and local bands touring New Zealand often perform there include Blerta, Trinity Roots, the New Zealand Guitar Quartet, Karen Pfeiffer, Scott Cook and The Kugels, The Mint Chicks, Bad Manners and Don McGlashan.

[17][18][19] The town is located near the southern end of a 17 km (11 mi) coastal plain known as the Barrytown Flats.

The flats are bordered by Paparoa National Park and the only breeding site of the Westland petrel (Procellaria westlandica).

There are significant deposits of ilmenite (titanium dioxide) in the Barrytown sands, and there have been several mining proposals, but the possible environmental consequences have been contentious.
