The Chattooga and Chickamauga Railway (reporting mark CCKY) is a short-line railroad which is headquartered in LaFayette, Georgia, USA.

The railroad operated 22 miles (35 km) of the Tennessee, Alabama and Georgia Railway (a.k.a.

the TAG route) from Chattanooga, Tennessee to Kensington, Georgia, which reverted to the Norfolk Southern System and was partially removed after the Dow Reichhold Specialty Latex LLC plant in Kensington closed in August 2008.

The CCKY is owned by the Georgia Department of Transportation, and operated by CAGY Industries.

The line does see operations of passenger trains between Chattanooga, Tennessee and Summerville, Georgia during weekends in the fall months and on other published dates during the year.
