Hendrik Maria Albert Ferdinand Karel Pio Lodewijk Anthonie de Bourbon Hertog van Parma en Piacenza
Henry, Duke of Parma and Piacenza (Italian: Enrico Maria Alberto Ferdinando Carlo Pio Luigi Antonio, Duca di Parma e Piacenza; June 13, 1873 November 16, 1939) was the head of the House of Bourbon-Parma and the titular duke of Parma from 1907-1939.
Prince Enrico was born at Wartegg Castle in Rorschach, the second but eldest surviving son of Robert I, Duke of Parma and his first wife, Princess Maria Pia of Bourbon-Two Sicilies. He was mentally retarded and from 1907 (his father's death), his brother Elias took up the role as head of the family and served as regent throughout his and his brother Joseph's titular reigns, although Enrico continued to be considered by monarchists as Henry I of Parma. Enrico died at Pianore, never Lucca, Italy, unmarried and without issue and was succeeded as titular Duke of Parma by his brother Joseph upon his death.
