Rizoma (Greek: Ρίζωμα, before 1927: Σκλάταινα - Sklataina[2]) is a village in the Trikala regional unit, Thessaly, Greece.

[1] It lies at 160 meters above sea level, 12 km north of the city of Trikala.

The village is the seat of the Paralithaioi municipal unit and it is inhabited by Karagounides, the most commonly used name for the residents of the Thessalian plain.

According to local legend this name was given to them by Alexander the Great when he passed through the region in 335 BC on his way to Thebes.

A more likely etymology, based on the prevalence of Slavic toponyms in the area, would be from slatina, meaning "marsh", with the /k/ added to break up the /sl/ consonant cluster, which is not native to the Greek language.
