The explanation of the coat of arms is "a red heart in a silver field, from which grows a three-pronged green conifer."

The coat of arms was designed by Olof Eriksson and approved by the Laukaa Municipal Council at its meeting on June 6, 1955.

[9] The name of Laukaa likely comes from the now obsolete word lauas (genitive: laukaan), stream pool, in this case referring to the Koivulahti bay in the lake Saraavesi.

The area of Laukaa was an important route to both the lake Keitele in the northwest and Rautalampi in the northeast.

This church was located near modern Tarvaala (aka Laukkavirta), which was therefore the original center of Laukaa.

[10] Saraakallio, the largest Stone Age rock painting site of Fennoscandia is located in Laukaa.

In summer the Kuusa Canal forms a unique backdrop setting for the outdoor stage.
