Peter Oliver (1594 – December 1648) was an English miniaturist. Born in Isleworth, Middlesex, he was the eldest son of Isaac Oliver, a French-born English portrait miniature painter, probably by his first wife. When he died, Isaac Oliver left his finished and unfinished drawings for Peter, with the hope that he would live to exercise the art of his father. Isaac's other sons appear to have been under-age at the time of his death, and were probably therefore by a later wife than Peter's mother. Peter Oliver resided at Isleworth, and was buried beside his father at St Annes, Blackfriars.
