Perkons (band) can also refer to the Latvian rock group.

In Latvian mythology, Perkons was the god of thunder, rain, mountains, oak trees and the sky, one of the most important deities in the pantheon.

By the 2nd century, Perkons was popular throughout the Baltic region. He was strongly associated with Dievs, though the two were clearly different.

The people sacrificed black calfs, goats, and roosters to Perkons, especially during droughts. The surrounding peoples came to these sacrifices to eat and drink together, after pouring beer onto the ground or into the fire for him. The Latvians also sacrificed cooked food before meals to Perkons, in order to prevent thunderstorms, during which honeycombs were placed into fires to disperse the clouds.

Perkons' family included sons that symbolized various aspects of thunderstorms (such as thunder, lightning, lightning strikes) and daughters that symbolized various kinds of rain.

Perkons appeared on a golden horse, wielding a sword, iron club, golden whip and a knife. Ancient Latvians wore tiny axes on their clothing in his honor.

The Finns assumed the name perkele to refer an evil spirit (not being on good terms with the Lithuanians at that time). Later with Christianity they also co-opted him for one of the titles of Satan. perkele is also one of the most common swearwords in the Finnish language; and frequently the first word taught to foreigners. (It is pronounced roughly PEHR-ke-LLEH with a strong rolled R.)
