Aino Kallunki (* in the 20th century) is a former Finnish biathlete .
Aino Kallunki started for Ounasvaaran Hiihtoseura and was one of the pioneers in women's biathlon in the early 1980s. She achieved her greatest success in the 1982/1983 season when she was third in the overall ranking of the World Cup, which was then still called the European Cup, behind Gry Østvik and Siv Bråten . She won a world cup race in the 5 km sprint in Falun in 1984 ahead of Anette Bouvin and Sanna Grønlid , in the 10 km individual she was third behind Østvik and Bråten at the same event.
At the world championships in 1984 she was first in the individual 21st and three days later in the sprint 25th. Her best world championship result was the tenth place at the world championships in 1987 in the individual over 10 km. Although she was considered the strongest biathlete in her country at the time, Tuija Vuoksiala and Pirjo Mattila were third and fourth, respectively, and Kallunki was seventeenth in the sprint. Between 1983 and 1988 Kallunki was Finnish champion four times, winning two titles each in the individual and in the sprint.
