Laconia is a region of Greece in the southeastern part of the Peloponnese peninsula. Its administrative capital is Sparta. The word laconic is derived from the name of the region by analogy—to speak in a concise way, as the Spartans were reputed by the Athenians to do.
Laconia is bordered by Messenia to the west and Arcadia to the north and is surrounded by the Myrtoan Sea to the east and by the Laconian Gulf and the Mediterranean Sea to the south. It encompasses Cape Malea and Cape Tainaron and a large part of the Mani Peninsula. The Mani Peninsula is in the west region of Lakonia.  The islands of Kythira and Antikythera lie to the south, but they administratively belong to the Attica regional unit of islands. The island, Elafonisos, situated between the Laconian mainland and Kythira, is part of Laconia.
The Eurotas is the longest river in the prefecture. The valley of the Eurotas is predominantly an agricultural region that contains many citrus groves, olive groves, and pasture lands. It is the location of the largest orange production in the Peloponnese and probably in all of Greece. Lakonia, a brand of orange juice, is based in Amykles.
The main mountain ranges are the Taygetus (2,407 m) in the west and the Parnon (1,961 m) in the northeast. Taygetus, known as Pentadaktylos (five-fingers) throughout the Middle Ages, is west of Sparta and the Eurotas valley. It is the highest mountain in Laconia and the Peloponnese and is mostly covered with pine trees. Two roads join the Messenia and Laconia prefectures: one is a tortuous mountain pass through Taygetus and the other bypasses the mountain via the Mani district to the south.
