Dunlop Sport is a British sports equipment manufacturing company established in 1910 that focuses on racquets and water sports, more specifically tennis, swimming, squash, padel and badminton. Products by Dunlop Sport include racquets, strings, balls, shuttlecocks, and bags. Sportswear and clothing line includes t-shirts, shorts, skirts, jackets, pants, socks, caps, sneakers, and wristbands.

Dunlop Sport is operated by SRI Sports, a subsidiary of Japanese conglomerate Sumitomo Rubber Industries, which acquired the Dunlop brand in 2017.

In the past, Dunlop also manufactured golf equipment.

Dunlop was established as a company manufacturing goods from rubber in 1889. The company entered the sporting goods market in 1910, when it began to manufacture rubber golf balls at its base in Birmingham. The company introduced the Maxfli golf ball in 1922.

Dunlop extended into tennis ball manufacture in 1924. In 1925, F A Davis was acquired, which had tennis racket manufacturing expertise. Dunlop opened acquisition discussions with Slazenger in 1927, but without success. In 1928, the sports division became a subsidiary of Dunlop Rubber named Dunlop Sports. Headquarters were relocated from Birmingham to Waltham Abbey in Essex.

The Dunlop Masters golf tournament was established in 1946. It was sponsored by Dunlop until 1982, and is now known as the British Masters.

In 1957, Dunlop acquired the golf club manufacturer John Letters of Scotland. In 1959 the Slazenger Group was acquired. The Dunlop "flying D" logo was introduced in 1960.

In the 1970s and 1980s, Dunlop was slow to adapt to the new materials that tennis rackets were increasingly being made from, believing that wood would remain the dominant material.
