Marco D'Arienzo (Naples, 24 April 1811 – 24 April 1877) was an Italian opera librettist.
D'Arienzo was a professional state official[1] and, at the same time, a writer and librettist.
From 1834 to 1837 he worked as a journalist for the Neapolitan newspaper L'Omnibus[2] and was also author of Neapolitan songs, many of which were set to music by Saverio Mercadante.
[2] His comic librettos have been described as "witty and well presented" in spite of their involved plots.
[3] Marco D'Arienzo was uncle of the composer Nicola D'Arienzo.
