Dunlop is a brand of tyre originally produced by the Dunlop Pneumatic Tyre Company from the end of the 19th century, taking its name from John Boyd Dunlop.

The brand is used for many other products made from rubber or with rubber components and some with a looser connection to rubber.

Ownership of the brand has become fragmented over the years.

Three main events contributed to this fragmentation: Currently, the Dunlop brand and logo is largely reunified under the ownership of Sumitomo Rubber Industries.

Various companies market products with the "flying D" logo or incorporate the word Dunlop in their trading name.
