The name Weyoun refers to a number of fictional characters from the television series Star Trek: Deep Space Nine, in which they are portrayed by Jeffrey Combs. These characters are, however, almost exclusively referred to in the singular as simply Weyoun, because each Weyoun is a clone of the original, and there is usually only one Weyoun at any one time; subsequent Weyouns are activated following the death of the previous clone.
