The city that hosted the men's doubles event at the 1893 U.S. Championships was Chicago.
The event was played at the St. George Cricket Club in Chicago from July 25 through July 29, 1893. This was part of the U.S. National Championships, the tournament that later became the US Open. The men's competition was staged separately from the women's events and men's singles that year.
The 1893 championships had an unusually dispersed schedule. Women's singles, women's doubles, and mixed doubles were held in Philadelphia, while men's singles took place at the Newport Casino in Newport, Rhode Island. That split schedule is the main source of confusion: Newport hosted the men's singles, not the men's doubles.
Clarence Hobart and Fred Hovey won the men's doubles title, defeating Oliver Campbell and Bob Huntington in the final. Chicago's role in the tournament was therefore specific to the doubles competition, rather than the entire championship.
