Krya Vrysi (Greek: Κρύα Βρύση, before 1927: Πλάσνα Plasna) is a town and a former municipality in Pella regional unit, Greece. Since the 2011 local government reform it is part of the municipality Pella, of which it is a municipal unit. The municipal unit has an area of 76.956 km. It is located 75 km west of Thessaloniki and 2 km east of the Early Neolithic settlement of Nea Nikomideia.

The town of Krya Vrysi, named Plasna before 1927, became an independent community in 1934, when it was separated from Valta. After the lake that covered the place was drained, the people had trouble finding drinkable water. When they found a source of cold, clear water, they called it "water from the Krya Vrysi (Cold Spring)", thus giving the town its name. The community Krya Vrysi became a municipality in 1990. The economy in the area is primarily based on agriculture with the farmers mainly growing corn and asparagus. They were also growing a great amount of Berley tobacco, until 2005 when the production was stopped in the region due to European Union's economical issues.

Krya Vrysi, being the centre for many smaller villages, is the host of various annual events. The Krya Vrysi Carnival has been the biggest regional multi-event including a large carnival procession. It takes place each year on the carnival three days' holiday since 1988 and has become an important tourist attraction for the town. During the Greek economic crisis it was temporarily paused (2009-2011). Another major annual event is the Agrotechnical Expo which is held in September. It combines a number of agricultural-related exhibits with a funfair (gr. πανηγύρι).

Krya Vrysi hosts at the Yiannis Tserkezidis Municipal Stadium the Apollon Krya Vrysi sports club founded in 1960. It currently competes in the 1. local league, but in the past it was promoted to the 2. national league. On the occasion of an initiative of the association of Veteran Footballers of Apollon Krya Vrysi for the creation of the Apollo Museum and the Folklore Museum of Krya Vrysi, the club invited the 2004 European Champion to the municipal stadium in September 2023 along with many other internationally known football personalities (see images below).
