In a vault at the BIE (initials for Bureau Internationale d'Eclairage, if I remember my French correctly) in Sevres, France. It is made of a platinum-iridium alloy. Replica kilograms are located at varous laboratories throughout the world, including one in the US.
Postscript: Previous responder is probably right about the name.

Securly in Bureau International des Poids et Mesures. The exact place is not specified for fear that manipulators may access it and replace it with a fake one to their advantage.
