The 1341 Kerala floods (also referred to as the Periyar River floods) refer to a deluge that occurred in present-day Kerala on that river during that year. There are no written historic treatise regarding this event. The present-day understanding regarding this event is centered around findings of the Pattanam archaeological excavations in the Kodungallur-North Paravur region and geological studies about the island of Vypin and Fort Kochi.

It is widely believed that excess siltation, caused by runoff from the Western Ghats through the Periyar River during the floods, led to change in the Periyar's course and destruction of the ancient natural port of Muziris. [2] The accretion following the deluge has brought tremendous changes to the shore between Alappuzha and Kodungallur, resulting in rejuvenation of new land masses like Vypin and soil deposits in the Panangad-Kumbalam region. Many historians also believe the floods were a major reason for the formation of Cochin Port and the estuary on Vembanad. [3]
