Cofachique (pronounced ko-fa-chee) is a ghost town situated along the Neosho River near the present-day city of Iola in Allen County, Kansas, United States. Being the first town established in Allen County in 1855, it was the original county seat. However, within five years the greater part of the town was moved to the new town of Iola, while the old site of Cofachique became farm land. The town was named in honor of an Osage chief known as Cofachique, who is said to have been particularly helpful to early settlers, bringing aid to the distressed and homeless. The name "Cofachique" appears to have origins with the Cofachiqui (or Cofitachiqui) tribe in South Carolina, who were Siouan speakers, and the Osage who settled this area were closely affiliated with the Siouan.
