Mary Ewing Outerbridge (February 16, 1852 – May 3, 1886) was an American woman who imported the lawn game tennis to the United States from Bermuda.
While posted to the British Bermuda Garrison in 1874, one of Wingfield's subordinates shared tennis equipment and rules with Outerbridge at Clermont, her family's home in Paget Parish that offered a large, flat lawn.
The sporting equipment was initially confiscated by customs officials, but her brother August used his connections in the shipping industry to have the supplies released.
First, memoirist Martha Summerhayes described playing tennis at Fort Apache, Arizona with Ella Wilkins Bailey, the wife of an army officer, on October 8, 1874.
Second, James Dwight played tennis with his cousin, Fred Sears, in Nahant, Massachusetts in 1875, raising the sport's popularity in New England.
