Gioacchino Toma (24 January 1836 - 12 January 1891) was an Italian art instructor and painter, noted primarily for historic, realistic and genre subjects in a Romantic style.
Toward the end of his life, Toma authored his autobiography, Memories of an Orphan (Ricordi di un Orfano, Giannini and Figli, 1886) relating a series of memories to his son, Gustavo: his difficult childhood; his tenacity; his desire for redemption; and his civil and political commitment.
