Klara Barlow (July 28, 1928 in Brooklyn, New York – January 20, 2008 in New York City) was an American opera singer who had an active international career from the mid-1960s through the 1990s.
A dramatic soprano, Barlow particularly excelled in portraying Strauss and Wagnerian heroines.
The 5-foot-11-inch-tall "platinum-blonde beauty" was ideal for playing the "Wagnerian blondes": roles like Elsa, Eva, Sieglinde, and Elisabeth.
Although she worked most often in the German repertoire, Barlow also sang roles from the Italian, French, and Czech repertories.
While her performance credits included leading roles at most of the world's major opera houses, she never achieved a high level of international fame.
She did not participate in any commercial audio recordings, although her voice is preserved on a few television and radio broadcasts made in Germany, Canada, and the United States.
