The 1952 Thomas Cup competition is an international team tournament for supremacy in men's badminton (its female counterpart is the Uber Cup). Beginning in 1948–49, it was held every three years until 1982 and thereafter has been held every two years. Twelve national teams contested for the Thomas Cup in the 1951-1952 badminton season, the tournament's second edition. According to the rules then in place Malaya was exempt from earlier ties (team matches), needing only to defend its title in a conclusive challenge round tie. The other contestants were divided into three regional qualifying zones, the Pacific, Europe, and Pan America, for the early ties. The winners of each zone then played-off in Malaya for the right to face Malaya in the challenge round. For a more detailed description of the Thomas Cup format see Wikipedia's general article on the Thomas Cup.
India qualified in the Pacific Zone by beating newcomers Thailand and Australia without the loss of a match (thus, 9–0 in each case). Six of the twelve teams in the tournament contested in the European zone. Here Denmark emerged victorious, but not without a tough fight from Sweden (6–3) in the zone semifinal. In the Pan American zone with only two teams, the United States defeated Canada 6–3, trumping a fine performance by Canada's Don Smythe.
The following four teams, shown by region, qualified for the 1952 Thomas Cup. Defending champion and host Malaya automatically qualified to defend the title it had won three years previously.
