Juha, Op. 74, is a verismo opera in three acts—comprising six tableaux—written from 1931 to 1934 by the Finnish composer Leevi Madetoja. The libretto, a collaboration between Madetoja and the Finnish soprano Aino Ackté, is based on Juhani Aho's 1911 novel by the same name. The story takes place on the border between West Karelia and East Karelia, and features as its central conflict a love triangle between the farmer Juha, his young wife Marja, and a Karelian merchant, Shemeikka. Disillusioned with rural life and seduced by promises of material comfort and romance, Marja runs away with Shemeikka; Juha, who maintains his wife has been abducted, eventually discovers her betrayal and commits suicide by jumping into the rapids.

Juha is a three-act opera by Aarre Merikanto, with a Finnish libretto by Aino Ackté based on the 1911 novel of the same name by Juhani Aho. Although completed by 1922, it was only finally staged at the music college in Lahti on 28 October 1963. The story is a drama of a love triangle: the older husband Juha, his young wife Marja, and her seducer the merchant Shemeikka. Set in the 1880s in Kainuu in northern Finland, the human tragedy is based around the harsh realities of a farming community and the clash of their lifestyle with the more worldly nomadic Karelians, represented by Shemeikka.
