ね, in hiragana, or ネ in katakana, is one of the Japanese kana, each of which represents one mora. The hiragana is made in two strokes, while the katakana is made in four. Both represent [ne].
As a particle, it is used at the end of a sentence, equivalent to an English, "right?" or "isn't it?" It is also used as slang in Japan to get someone's attention, the English equivalent being "hey" or "hey, you."
