The US Open depends on which sport you mean:

  • Tennis (US Open 2026, New York): Officially scheduled from Sunday, August 23 to Sunday, September 13, 2026 , with the main singles draw starting August 30, 2026.
  • Golf (U.S. Open 2026, Shinnecock Hills): The championship is set for June 18–21, 2026 in Southampton, New York.

If you meant the tennis Grand Slam (the one at Flushing Meadows in NYC), people usually refer to that when they say “US Open,” so the answer is late August to mid‑September 2026 , with most big matches in the first two weeks of September.

Quick Scoop

1. Tennis US Open 2026

  • Runs August 23 – September 13, 2026 in New York City at the USTA Billie Jean King National Tennis Center.
  • The main draw (the big-name matches you see on TV) kicks off August 30, 2026 and closes with the finals on the last weekend.
  • It’s the last Grand Slam of the tennis season, so storylines often include: rankings battles, “last chance of the year” for a major, and possible farewell runs for aging stars.

Think of it as New York’s late‑summer sports festival: hot weather, night matches, and packed crowds under the lights.

2. Golf U.S. Open 2026

  • Held June 18–21, 2026 , at Shinnecock Hills Golf Club in Southampton, NY.
  • This is a four‑day major on the PGA/USGA calendar, very different vibe from tennis: early summer, links-style golf, tradition-heavy atmosphere.

3. Which one are people usually asking about?

When someone casually types “when is the us open” , they’re most often talking about:

  1. Tennis US Open (New York, late August–September), or
  2. Golf U.S. Open (rotating golf course, usually mid‑June).

Right now, the more “trending” fan discussions lean toward the tennis dates in late August and early September 2026, since it’s part of the big Grand Slam narrative and sits right before the fall sports season kicks into gear.

4. Super short answer you can reuse
