AAC Richmond is a white-hulled, spring oat (Avena sativa L.) cultivar developed at the Ottawa Research and Development Centre of Agriculture and Agri-Food Canada in Ottawa, ON. It was supported by the Ontario Cereal Crops Committee in January 2013 for registration and was registered on 20 Feb. 2014 (Canadian Food Inspection Agency no. 7488). AAC Richmond was later maturing and taller and showed higher grain and straw yield than check cultivars in eastern Canada. It was highly resistant to crown rust (Puccinia coronata Corda f. sp. avenae Eriks.).
