Pavillion is a town in Fremont County, Wyoming, United States.

In 2008, rural residents five miles east-northeast of Pavillion complained of discolored water, foul smells and illness that they suspected was due to fracking, and the EPA opened an investigation.

[6][7] In 2010, the EPA investigators warned the affected rural residents not to drink their water after finding benzene, naphthalene, phenols, and metals in the water and recommended that the affected rural residents use fans while bathing or washing clothes to avoid the risk of explosion.

[9][10] Eventually, in 2016, a study confirmed that chemicals used in fracking impact drinking water that is generated from wells.

[11] According to the United States Census Bureau, the town has a total area of 0.21 square miles (0.54 km2), all land.

About 3.3% of families and 3.5% of the population were below the poverty line, including none of those under the age of eighteen and 7.1% of those 65 or over.

Public education in the town of Pavillion is administered by Fremont County School District #6.
