Kappa (upper case Κ, lower case κ) is the tenth letter of the Greek alphabet. In the system of Greek numerals it has a value of 20.

In textual criticism, the Byzantine text-type (from Κοινη, Koine, the common text).

The letter κ is almost always Latinized as 'c' when translitterating Greek text into English - even before 'e' and 'i', where English 'c' is pronounced as 's'. Hence the English pronunciation of Greek names only seldom corresponds with the original Greek pronunciation.ca:Kappa de:Kappa el:Κάππα es:Κ fr:Kappa nl:Kappa pl:Kappa pt:Κ sv:Kappa zh:Κ
