AS Karditsas B.C. (Greek: Α.Σ. Καρδίτσας K.A.E.), is a Greek professional basketball club that is based in Karditsa, Greece. The club's full name is Athlitikos Syllogos Karditsas (Αθλητικός Σύλλογος Καρδίτσας), which is also abbreviated as A.S.K. (Α.Σ.Κ), or A.S. Karditsas (Α.Σ. Καρδίτσας). The club's colors are white and blue.
ASK Karditsas was founded in its current form in 2006, as a result of a merger between the clubs Α.S. Karditsas 21st Century and Amila Karditsas. Α.S. Karditsas 21st Century and Amila Karditsas were themselves formed from earlier mergers. Α.S. Karditsas 21st Century was formed from a merger between Aiada Karditsas and Sports Club Karditsas, while Amila Karditsas was formed from a merger between G.S. Karditsas (where the well-known Greek player Giannis Bourousis began playing youth team basketball), Anagennisi Karditsas, and Amila Karditsas.[3] As a result, it is generally considered that the present club incorporates the history and tradition of all of the previous clubs.
