United Municipalities of Loodon was a short-lived confederation of a group of cities, villages and settlements near and around the mouth of the Loodon river in the middle of the 18th CSR. United to be able to better defend their lands from occasional xornerian raids, they were overrun by the Kareden just several years later.

Their main city was Oyangaltans, located at the mouth of the Loodon river.

Loodon started by copying the confederation model of the United Municipalities of Loodon when they organized their cooperative.
