Dionisio Fierros Álvarez (5 May 1827 – 24 June 1894) was a Spanish painter in the Romantic style who specialized in historical and costumbrista scenes.

[2] He was born in Ballota, but left his home town at the age of fourteen for Madrid, where he found a position as an apprentice to a tailor.

Later, it is believed, he became a servant for the Marqués de San Adrián [es], who had an extensive art collection.

He made his exhibition début in 1858, with five portraits and three miscellaneous scenes, shown in Santiago de Compostela, where he was living at the time.

[1] At the National Exhibition of Fine Arts in 1860, he won a prize for his painting of a pilgrimage to Santiago and, in 1862, came in at second place for his depiction of people leaving a mass there.
