The 2018 Real Tennis British Open was the 40th edition of the British Open since it became an annual event in 1979. The men's event was held at the Queen's Club in London between November 11–20, 2018 and was organised by the Tennis and Rackets Association. It formed part of the qualifying series for the 2020 Real Tennis World Championship.[1] [2] The women's event was held at the Seacourt Tennis Club on Hayling Island between April 4–7, 2018.[3] The men's draw was the fourth and final grand slam event of the year.
