Taavi "Dave" Komonen (December 16, 1898 – April 19, 1978) was a Finnish-Canadian athlete, who mainly competed in marathon running.

Taavi Komonen was born in Käkisalmi, Karelia, which then belonged to Finland but was invaded by the Soviet Union during World War II.

In Toronto he looked for work in the construction industry, but because of the Great Depression and his lack of English he did not find a steady job and was unemployed for periods of time.

After the race Komonen sold his running shoes for four dollars to pay for a ticket back to Toronto.

On May 5, 1934, five years to the day from Komonen's arrival in Canada, he filed naturalization papers, aiming to compete in the 1934 British Empire Games in London.

However, Canadian law required a three month waiting period for citizenship, meaning that Komonen would miss by three weeks the marathon trial scheduled for July.
