Konstancin-Jeziorna [kɔnˈstaɲt͡ɕin jɛˈʑɔrna] is a spa town in Piaseczno County, Masovian Voivodeship, Poland, with 17,566 inhabitants (as of March 2011, according to GUS). It is located about 20 km (12 mi) south of downtown Warsaw and is a part of the Warsaw metropolitan area.

The town was created in 1969 through combining neighbouring towns: holiday resort Skolimów-Konstancin and industrial Jeziorna with a number of villages.

The town, a 19th-century health spa, sits on the administrative border of the capital city, Warsaw. The town is known for its historic villas as well as newly built mansions, a shopping center in a restored 19th-century mill and is the home of the American School of Warsaw.
