1955 Thomas Cup knockout stage

The knockout stage for the 1955 Thomas Cup began on 24 May 1955 with the first-round knockout and ended on 5 June with the final tie.

Qualified teams
The teams that won their zonal tie qualified for the final knockout stage.

First round
In the first round of the inter-zone playoffs India avenged its 1952 loss to the US by winning 4 of 5 singles matches and holding its own in doubles to defeat the Americans 6–3. Although Australia played some competitive matches against European powerhouses Denmark, it was unable to win any of them (0–9).

Denmark vs India
Young Kobbero was the star of the inter-zone final between Denmark and India. He won all four of his matches which included a fine three game duel with India's stylish Nandu Natekar, leading Denmark to a 6–3 victory. Thus, Denmark emerged as the challenger to cup-holder Malaya.

Malaya vs Denmark
The competitive swan song of Malaya's venerable Wong Peng Soon was successful though he dropped a game to both Kobbero and Jørn Skaarup. Eddie Choong, with two All-England singles titles already to his name, made his Thomas Cup debut by beating both Kobbero and Skaarup in straight games. Ong Poh Lim was once again stalwart, winning his match at third singles and both of his doubles partnered by veteran Ooi Teik Hock. The Danes could muster only one victory which came in doubles and largely from the efforts of Kobbero's partner Jorgen Hammergaard Hansen whose powerful smash lived up to his name. Winning 8 matches to 1, Malaya thus retained the Cup.
