Adolf von Trotha (March 1, 1868, Koblenz, Rhine Province – October 11, 1940) was a German admiral in the Kaiserliche Marine from Koblenz, Rhenish Prussia.
Trotha was the third son of Karl von Trotha (1834–1870), who fell in the Franco-Prussian War, when his son was only two years old.
Trotha married Anna von Veltheim (15 January 1877 - 8 August 1964) on 4 June 1902, the daughter of Fritz von Veltheim and Elizabeth von Krosigk.
Trotha entered the imperial navy in 1886 as an officer candidate and was promoted to Leutnant zur See in 1891. He served as a commander of the torpedo boat D3 and as a Navigations officer on the small cruiser SMS Seeadler.
