Harrentown or Harrenton is a town located outside of Harrenhal in the riverlands. It lies on the northern shore of the Gods Eye.
The multitude of lords, retainers, and smallfolk who came to Harrenhal for the Great Council of 101 AC led to Harrentown briefly being considered the fourth largest city of the Seven Kingdoms.
