Joan Grehan

Joan Grehan (5 January 1920 – 25 November 2007) was a New Zealand artist.

Grehan was born Joan Greenwood Brodie in 1920 in Whanganui. Her parents were Archibald Douglas Brodie and Marjorie Gascoyne Greenwood, who married in 1916. Grehan attended Whanganui Girls' College and studied fine art at the University of Canterbury, then later at the Camberwell College of Arts in London. While at Canterbury she studied under noted Christchurch artists Cecil F. Kelly and Archibald Nicholl. She lived and worked overseas for 30 years in Australia, Cyprus, Uganda, Lebanon, Italy and France before returning to New Zealand in 1983. Grehan studied ceramics under Alfredo Galicamo, specialising in modelling mythical beasts and figures.

Much of Grehan's art was about women, and often featured symbols linked to nature, wisdom and sensuality. In 2014, the Joan Grehan Estate gifted 462 of her works to the Sarjeant collection.

Grehan's works are held in the collections of Sarjeant Gallery, Auckland Art Gallery Toi o Tāmaki, and Museum of New Zealand Te Papa Tongarewa.
