Aino Seppo is a Finnish actress whose film career is inextricably linked to the works of director Aki Kaurismäki. She is renowned for her ability to embody characters of great humanity through an understated, naturalistic, and often minimalist performance, devoid of dramatic excesses.

Seppo has distinguished herself by portraying ordinary women, often from working-class backgrounds or in situations of economic and social precarity, who face life's adversities with quiet dignity and silent resilience. Her screen presence is characterized by profound authenticity and a moving ability to express complex emotions with few gestures or glances.

Among her most significant roles are her performances in Kaurismäki films such as *Kauas pilvet karkaavat* (Drifting Clouds, 1996), *Mies vailla menneisyyttä* (The Man Without a Past, 2002), *Le Havre* (2011), and *Toivon tuolla puolen* (The Other Side of Hope, 2017), works that have contributed to defining her distinctive style in Finnish and international cinema.
