The International Emmy Award for Best Performance by an Actress is an award presented annually by the International Academy of Television Arts and Sciences (IATAS). The award honors the best performance by an actress in a made for-television fiction program.

The International Emmy Awards, or International Emmys, are part of the extensive range of Emmy Awards for artistic and technical merit for the television industry. Bestowed by the New York–based International Academy of Television Arts and Sciences (IATAS), the International Emmys are presented in recognition to the best television programs initially produced and aired outside the United States. The awards are presented at the International Emmy Awards Gala, held annually in November in New York City. It attracts over 1,200 television professionals. The first International Emmys ceremony was held in 1973, expanding what was originally a U.S.-only Emmy Award.
