The Kentucky Three-Day Event, currently the Land Rover Kentucky Three-Day Event due to sponsorship, is an eventing competition held at the Kentucky Horse Park in Lexington, Kentucky. Land Rover Kentucky is a CCI5*-L eventing competition. Five stars is the highest level of competition in the sport, the same level of competition as Eventing at the Olympics and the World Equestrian Games. The event is sponsored by Land Rover. Prize money of $400,000 is distributed among the top placings with $110,000 as well as a Rolex watch awarded to the first place horse and rider.

Although the event's name continues to reflect its roots as a three-day competition, the Kentucky Three-Day Event currently takes place over four days (Thursday through Sunday). Due to large number of entries, both Thursday and Friday are devoted to the dressage test. Cross-country is on Saturday, and show jumping is on Sunday.

The Kentucky Three-Day Event is held the last weekend of April, the week before the Kentucky Derby. It is one of the three events in the Rolex Grand Slam of Eventing.
