Joan Kyrle Evans, PBVM, is a retired Australian religious sister born in 1931 who was based in the Klong Toei slums in Bangkok, Thailand. She is a member of the Western Australian Congregation of Presentation Sisters. Evans is a charity activist, who helps the needy youth and families in the slums of the Thai capital. Each fortnight, Evans' project supports around 100 babies with deliveries of powdered milk.
Prior to her work in Thailand, Evans taught mathematics and geography in schools throughout Western Australia. Postings included Iona Presentation College in the Perth suburb of Mosman Park, and Stella Maris Presentation College in the midwestern town of Geraldton. In 1992 she arrived in Thailand and established several charitable projects for the needy in Bangkok. Evans returned to Perth in early 2017, at age 84. Her volunteers continue a number of her projects.
On 11 June 2018, Evans was made an Officer (AO) in the General Division of the Order of Australia, "for distinguished service to the international community of Thailand through humanitarian assistance programs for the disadvantaged, and to improving the lives of women, children and the elderly".
Sister Joan Evans died on 29 September 2025 in Perth, W.A., Australia.
