Arturo Corrado Luigi Triangi, Conte di Maderno e Laces (18 February 1864 in Fiesole – 3 March 1935 in Florence) was an Italian admiral.

Over the next two years on board Flavio Gioia, Triangi voyaged to South America, touching the major Atlantic and Pacific ports of the continent.

[3] He was tasked with maintaining control of the Tripolitanian coast and suppressing the smuggling of weapons in to Ottoman and indigenous forces who opposed the Italian invasion.

[2] From 1 May 1913 until 28 August 1914, Triangi was chief of staff of the 2nd naval squadron, serving aboard the battleship Regina Elena and then the dreadnought Dante Alighieri.

At the outbreak of the World War I he was seconded as chief of staff of the maritime military department of Venice, a position he held from 1 October 1914 to 1 February 1917.

[cleanup needed] From 18 February 1917 he was transferred to an auxiliary role because of his age, but despite this Thaon di Revel appointed him deputy chief of staff of the navy, a position he held until 16 June 1917.

[2] A political crisis developed in the Boselli government in 1917 over the exceptionally high shipping losses Italy was suffering as a result of Imperial German Navy submarine activity, seriously disrupting the country's war industries.

During a closed-door meeting in the Chamber of Deputies, he argued that the crisis in maritime transport could not easily be resolved, because the April 1917 entry of the United States into the war was placing significant new demands on merchant shipping, meaning less was available for Italian use.
