The name is of Slovak origin and belongs to the oldest recorded Slovak settlement names in Spiš. It was originally the name of the stream Lěvoča, a tributary of the river Hornád (present-day Levočský potok). The name probably derived from the adjective lěva (left, a left tributary); the linguist Rudolf Krajčovič has also suggested as an origin the word lěvoča meaning "regularly flooded area”.

Levoča is located in the historical region of Spiš, which was inhabited as early as the Stone Age. In the 11th century, this region was conquered and, subsequently, became part of the Kingdom of Hungary and remained such until 1918. After the Mongol invasions of 1241/1242, the area was also settled by Germans (later known as Zipser Germans). The town became the capital of the Association of Spiš Germans, with a form of self-rule within the Kingdom of Hungary. The oldest written reference to the city of Levoča dates back to 1249. In 1317, Levoča (at that time generally known by the German name of Leutschau - see Chronology below for lists of changing names) received the status of a royal town. In 1321, a wide-ranging right was granted, enticing merchants, craftsmen, and mine owners to settle in this town.

In the 15th century, the town, located on an intersection of trade routes between Poland and Hungary, became a rich center of commerce. It exported iron, copper, furs, leather, corn, and wine. At the same time, the town became an important cultural centre. The English humanist Leonard Cox taught around 1520 in a school in Levoča. The bookseller Brewer from Wittenberg transformed his bookstore into a prolific printing plant that lasted for 150 years. Finally, one of the best-known medieval woodcarvers Master Pavol of Levoča settled here.

The town kept this cultural and economic status until the end of the 16th century, despite two damaging fires: the first in 1550 destroyed nearly all of the Gothic architecture and another in 1599. In this period of prosperity, several churches were built, and the town had a school, library, pharmacy, and physicians. There was a printing press as early as 1624. Levoča was a center of the Protestant Reformation. The town started to decline during the anti-Habsburg uprisings in the 17th century.
