The tournament was held from August 23 to August 28. It was the 6th United States National Championships and the second Grand Slam of the season.

The men's and women's championships would be held on separate months for several decades. US Open 1886: August 23–28, 1886 at Newport Casino. Men's singles: Richard D. Sears — 6th major title.
