Aarre Merikanto (29 June 1893, Helsinki, Grand Duchy of Finland – 28 September 1958, Helsinki, Republic of Finland) was a Finnish composer. He was the son of Liisa Häyrynen and the famous romantic composer, professor Oskar Merikanto. His childhood he spent in Vilppula, Finland. From year 1919, he was married to Meri Grönmark. He is considered a key figure in early Finnish modernism (together with Väinö Raitio and Ernest Pingoud) and several of his works, most notably the opera Juha, have obtained posthumous attention. As professor of composition in the Sibelius Academy (1951–1958) Merikanto taught several Finnish composers of the next generation, including Einojuhani Rautavaara, Usko Meriläinen, Aulis Sallinen and Paavo Heininen.
