Raymond Henry "Sandy" Adsett MNZM (born 27 August 1939) is a New Zealand visual artist and educator.

Adsett has cited the mentorship of the Ngāti Porou master carver Pine Taiapa as the most significant influence on his life as an artist and educator.

In 1991, Adsett became a principal tutor at Tairawhiti Polytechnic in Gisborne, working in the Toihoukura School of Māori Visual Arts.

[8][9][10] In 2002, Adsett returned to Hawke's Bay, where he set up the Toimairangi School of Māori Visual Culture within Te Wānanga o Aotearoa in Hastings.

In 2021 a major retrospective of Adsett's work was organised by Pātaka Art + Museum, curated by Reuben Friend.
