Coastlands is a beach settlement in the Whakatāne District and Bay of Plenty Region of New Zealand's North Island. It is located north of Whakatāne, directly across the Whakatāne River.

A tsunami siren is located at Coastlands.

According to tradition, when the Mataatua waka first arrived at Whakatāne from Hawaiki 600 years ago, the men left the women alone in the canoe while they went to visit the shore. The canoe started to drift back out to sea. Wairaka, the daughter of captain-navigator Toroa, seized the paddle, and brought the waka back to shore. She forbade the tapu forbidding women to handle canoes, shouting "Kia Whakatane au i ahau", translating as "I will act the part of a man"; this phrase is the origin of Whakatāne's name.

Other traditions suggest it was Muriwai, Toroa's sister, who had brought the canoe to shore.

The Lady on the Rock statue, a bronze statue at the top of the Turuturu Rock at the mouth of the Whakatane River, commemorates the bravery of Wairaka. It was unveiled in 1965 as a memorial to the wife of Sir William Sullivan.

The area is within the rohe (tribal area) of the Ngāti Awa iwi. It is the site of a urupa, or graveyard, which is still used by Ngāti Awa.

The local hapū, Ngāi Taiwhakaea II, has a marae called Taiwhakaea and a meeting house called Taiwhakaea II.

In October 2020, the Government committed $305,099 from the Provincial Growth Fund to upgrade the marae. The upgrade was expected to create 8 jobs.

There was an attempted robbery of a berry farm and cafe in Coastlands in February 2017. There were 60 customers and 15 staff inside at the cafe at the time, but only two people were injured.

A 7.44-hectare (18.4-acre) farming block was opened for development in November 2018. A planning permission application was filed in December 2019 to build a beachside retirement village on the site.
