Which country has won the most Thomas Cup badminton titles?

Indonesia has won the most Thomas Cup badminton titles, with 14 championships.

The Thomas Cup is the world team championship for men's badminton. Indonesia first won it in 1958 and built its record through repeated success across the late twentieth and early twenty-first centuries. Its victories have featured generations of elite singles and doubles players, making the country's team tradition central to the tournament's history.

China is the nearest rival in Thomas Cup history, while Malaysia was an early power and India won its first title in 2022. The event is played as a tie between nations rather than as an individual tournament: each tie includes singles and doubles matches, and the first team to reach the required number of wins advances.
