On your right hand.
It is traditional to wear a wedding band on the forth left finger. Some European people wear their wedding bands on the right hand. If you want to wear your wedding band on a different finger then do so.
Catholics and many Christians (which include Protestants) wear it on the left hand, Jews (if I'm not mistaken) wear theirs on the right hand. It is said that you wear a wedding ring on your left hand because it is closest to your heart.
Traditionally, wedding rings are worn on the left hand.
In the US it is customary to wear a wedding ring on the Left Hand.
