Aimo Anshelm Aaltonen (10 December 1906 – 21 September 1987) was a Finnish construction worker, carpenter, and politician.

Aaltonen was born in Pargas and was the middle of 3 sons, and had multiple jobs by the time he was ten, and became a carpenter at 13.

Shortly after he returned to Finland, he was arrested on sedition charges and spent ten years in prison.

In 1944 he was freed as a result of the Moscow Armistice of 19 September 1944, which led to the legalisation of the Communist Party of Finland (SKP).

He was a member of the Parliament of Finland from 1945 to 1962, representing the Finnish People's Democratic League (SKDL).
