Emma Sandys (born Mary Ann Emma Sands) (1843 - 1877) was a 19th-century English painter.
Sandys was born in Norwich, England in 1843. She was taught by her father, Anthony Sands, and worked in portraits in both oil and chalk, often in medieval or period dress. Her earliest dated painting is marked 1863 and she exhibited her works in both London and Norwich between 1867 and 1874.
Sandys did most of her work around Norwich but may have spent time in the studio of her brother, Frederick Sandys, in London.
She died Norwich in November 1877.
