Yvonne Gregory (1889–1970) was a British society photographer.

Gregory married fellow photographer Bertram Park in 1916.^[1] Gregory, Park and Marcus Adams established themselves as the "Three Photographers" and based their collective studio at 43 Dover Street in Mayfair.^[2][3] Their studio was initially funded by the Egyptologist George Herbert, 5th Earl of Carnarvon.^[1] Gregory and Park would collaborate on works, and Gregory would also pose for Park.^[4] She joined the Royal Photographic Society in 1926 and gained her Associate the same year and Fellowship in 1928.^[5] She also exhibited regularly in RPS exhibitions.

Park and Gregory published several books together including 1935's The Beauty of the Female Form.^[4] The book arose from work they had produced for the first international photographic salon, held in Paris in 1933.^[4] Gregory, with and without Park, published extensively in nudist and naturist books and magazines from the 1930s onwards, a subject discussed in detail in Annebella Pollen's 2021 book, Nudism in a Cold Climate.^[6]
