Martin + Osa (Martin & Osa) was a brand of clothing and stores developed by American Eagle Outfitters. The store's name and inspiration came from Martin and Osa Johnson, a husband and wife team from southeast Kansas who explored Africa and the South Pacific Islands, chronicling their travels in photographs and diaries. Martin + Osa targeted 25 to 40-year-old customers and offered classic and contemporary clothing, with an emphasis on denim. In 2016 the Martin and Osa Johnson Safari Museum acquired the Martin + Osa trademarks.
