Murder at the New York World's Fair is a novel that was published in 1938 by Phoebe Atwood Taylor writing as Freeman Dana.

Mrs. Daisy Tower is 67, the widow of a former governor, and for the last year has undergone the untender attentions of her nephew Egleston and his overbearing wife Elfrida during her convalescence from pneumonia and a broken hip.

She and her fellow passengers find themselves in a screwball comedy fix, set against the pageantry of opening day under the shadow of the Fair's spectacular trylon.

Daisy must not only identify the corpse and the murderer, but save the Fair from destruction by a maniac—and find a way to get Egleston and Elfrida out of her hair.

Bennett Cerf, publisher of Random House, commissioned Phoebe Atwood Taylor to write this mystery as part of the festivities surrounding the 1938 New York World's Fair.
