Communia is an unincorporated community located in Clayton County, Iowa, United States, in the south half of section 8, Volga Township.

In early 1847 a group of pioneers, consisting of nine Germans (among them, Heinrich Koch) and one Frenchman, met in St. Louis to set off for new land under the direction of Joseph Venus.

After buying necessary provisions, the group left on foot with only one wagon and three oxen to the northwestern area of Volga Township.

The men welcomed anyone who wished to join, no matter how much or how little they contributed, and over the next few years the colony began to flourish.

Despite the great success of the colony, the area dissolved in 1858 after much of the land and property was sold off by various families.
