Schaller is a city in Sac County, Iowa, United States.

Settlers came mostly from Germany, England, Canada, New York, and eastern Iowa.

Throughout the middle part of the twentieth century a major industry consisted of the packers of Bango and Jolly Time popcorn.

The presence and size of these two companies helped Schaller become "The Popcorn Capital of the world."

Popcorn is still a major area industry, but the companies moved on to other locations in the 1980s.

Corn (seed and feed), soybeans, and feeder cattle are the major products of the area.
