Yes, there are several famous events that could be what “grand derby” refers to, depending on what you mean and where you are.

What “grand derby” might mean

  • In UK horse racing, the Epsom Derby is often just called “the Derby” and is one of the biggest flat races in the world, run at Epsom Downs each year.
  • In US horse racing, the Kentucky Derby at Churchill Downs is the most famous “Derby,” known as “the greatest two minutes in sports.”
  • There are also large “Derby” events in other contexts (for example, football rivalries are often called “derbies,” like local derbies between big clubs), but those are usually called “derby matches” rather than “grand derby.”

Current big Derby-style races

  • The Betfred Derby Festival at Epsom Downs in 2026 runs on Friday 5 June, with Derby Day on Saturday 6 June, featuring the main Derby race at around 4 pm.
  • The 2026 Kentucky Derby is scheduled for May 2, 2026, at Churchill Downs, as part of a full Derby weekend with tickets and hospitality packages already promoted.

If you meant a specific “Grand Derby”

  • There is an Algarve Great Derby in Portugal, which is a one-loft pigeon race with a multi‑stage format and a big final over about 500 km.
  • Other regions and sports sometimes brand local or regional events with names like “Great Derby” or “Grand Derby,” but these are usually more niche or local compared with Epsom or the Kentucky Derby.

If you can say which sport (horse racing, football, something else) or which country you mean, a much more precise answer about “the” grand derby can be given.
