Duke of Arcos (Spanish: Duque de Arcos) is an hereditary title in the Peerage of Spain, granted by Isabella I in 1493 to Rodrigo Ponce de León, then 4th Count of Arcos.[2][3] The dukedom is among the first 25 titles which reached the rank of Grandee of Spain 1st Class, in 1520. Nowadays however, all Grandees are of the same class.
The title makes reference to the town of Arcos de la Frontera in Cádiz.
The 4th Duke of Arcos was a character in the opera called Salvator Rosa (1874) by Antônio Carlos Gomes.[4]
