	'''Kappa''' (uppercase '''Κ''', lowercase '''κ''' or '''ϰ'''; Κάππα) is the 10th letter of the [[Greek alphabet]], used to represent the [[voiceless velar stop]], or "k", sound in [[Ancient Greek\|Ancient]] and [[Modern Greek]]. In the system of [[Greek numerals]] it has a value of 20. It was derived from the Phoenician letter [[Kaph]]. Letters that arose from kappa include the Roman [[K]] and Cyrillic [[Ka (Cyrillic)\|К]].

	Greek proper names and placenames containing kappa are often written in English with "c" due to contemporary rendering into the [[Latin alphabet]] by ancient Romans. However, modern transliteration of the Greek language invariably use the letter "k". Compare ''Κυνοσκεφαλαι'', ''[[Cynoscephalae]]'' (ancient placename); ''κυνος κεφαλαι'', ''kunos kephalai'' (phrase), meaning "[[dog]]'s [[head]]s".
