Martti Olavi Talvela (February 4, 1935 – July 22, 1989) was a Finnish operatic bass.

Born in Hiitola, Finland (now in the Republic of Karelia), the eighth of ten children he studied in Lahti and Stockholm, and made his operatic debut in Helsinki in 1960 as Sparafucile. He trained as a boxer in his youth and developed the stamina necessary for the biggest roles. Originally Talvela was educated as a primary school teacher in Savonlinna, Eastern Finland (1952–1956), and he worked in that occupation at three schools (1957–1960). He sang at the Stockholm Royal Opera in Sweden from 1961 to 1962, before becoming a regularly employed singer at the Deutsche Oper (German Opera) of Berlin in 1962, the same year as his debut at Bayreuth.
