The year 1931 in tennis was a complex mixture of mainly amateur tournaments composed of international, invitational, national, exhibition, team (city leagues, country leagues, international knock-out tournaments) events and joined by an up-and-coming Pro Tour both on competitive and exhibitional levels.

At the end of the pro season the champion title was awarded. Bill Tilden held the title at the end of the year. He also ran his own pro organization called the Tilden Tennis Tours and toured the world with a series of pro exhibition-like matches. The European professionals of Germany, France, Britain, Austria, the Netherlands and Switzerland founded the International Federation of Professionists and Professionals headed by Roman Najuch to represent their interest against the International Lawn Tennis Federation (ILTF). There were a few occasional professionals against amateur challenges as well held in team competition format. The amateur events were almost all co-educated thus the majority included a mixed title contest. Irishman George Lyttleton-Rogers dominated the European scene winning eight singles titles, all of which were confined to French and Italian championships. Ellsworth Vines was the dominant male player on the North American tour. The women's most successful players were Miss Elizabeth Ryan in North America and Cilly Aussem in Europe and in South America. Australian tennis life was figureheaded by Jack Crawford.

The most prestigious team cups were the Wightman Cup for ladies and the Davis Cup (called the International Lawn Tennis Challenge) for men. The 1931 Wightman Cup was its 9th edition and was organized by the United States Tennis Association between the teams of Great Britain and the United States. The 1931 International Lawn Tennis Challenge was its 26th edition and was organized by the ILTF. The Americas Zone was split into the North/Central American Zone and the South American Zone. The winner of each sub-zone would play to determine who moved to the Inter-Zonal round. 22 teams entered the Europe Zone, while 7 participated in the Americas Zone. The United States defeated Argentina in the American Zone, but would then lose to Great Britain in the Inter-Zonal play-off. France defeated Great Britain in the Challenge Round, giving France their fifth straight title. The final was played at Stade Roland Garros in Paris, France, on 24–26 July.

February

Dutch player Hendrik Timmer was hit by a disease and missed the season. Two Dutch female players announced their engagements and subsequently their retirement from professional sports. Netherlands' number one Kea Bouman married in Almelo and moved to Java while second ranked Margaretha Dros-Canters married and decided to dedicate herself solely to her marriage after the season.
The strike of the German tennis players continued from last month and caused a major setback on the indoor tournaments. Thus the German International Covered Courts tournament field was dominated by foreign and senior players such as World War I French veteran Eugene Broquedis who reached the semifinal of the singles and the final of the doubles competition despite being 45 years old and having his right shoulder and two fingers paralyzed in the war.
Newcomer young German tennis player Harry Schwenker shocked the tennis world by defeating Italian champion Umberto De Morpurgo in the semifinals of the Berlin Covered Court Championships. He went on to defeat Austrian champion Hermann Artens in the final of his debut tournament.

Notes

File:Bill Tilden in color.jpg]]

{{note label|HunNat|a|a}}The men, women and mixed contests were held at different locations at different dates. The final was suspended due to Béla von Kehrling's schedule conflict (he travelled to Wimbledon), and was finished later. The same reason forced him to withdraw from the doubles and mixed doubles draws as well.{{cite journal|editor=Béla Kehrling|editor-link=Béla Von Kehrling|url=https://epa.oszk.hu/02100/02127/00048/pdf/EPA02127_tennis_es_golf_1931_3_014.pdf|volume=14|series=III|page=19|title=Nemzeti férfi egyes, férfi páros és vegyespáros bajnokságok|trans-title=Hungarian National Men's singles doubles and mixed doubles championships|journal=Tennisz és Golf|date=18 June 1931|publisher=Egyesült Kő-, Könyvnyomda, Könyv- és Lapkiadó Rt|location=Budapest, Hungary|language=hu|access-date=25 January 2012}}
{{note label|Qual|b|b}}Both Roderich Menzel and Gustav Jaenecke reached the main draw from the qualifying rounds.
{{note label|USNat|c|c}}The men's, women's and mixed contests were held at different locations at different dates. The West Side Tennis Club of Forest Hill, California, organized the men's (September 5–12), women's singles and doubles (17–22 August) while the men's and mixed doubles took place in Chestnut Hill, Massachusetts, from 24 to 29 August.

{{note label|Badmix|d|d}} The mixed doubles final of the Bad Homburg Championship remained unplayed. The prize money was halved between the finalists.
{{note label|Meran|e|e}}The women's championships were played in a round-robin format (meaning players played against all the other players in their group).
{{note label|HunCze|f|f}}Several matches were suspended and cancelled due to hailstorms and blizzards. Many players travelled home and granted walkovers to their opponents.
{{note label|score1|g|g|{{note label|score2|h|h}}}}Sources differ regarding the scores of certain finals of this event. Tennisz és Golf of Budapest (g) and The Argus of Melbourne (h) claim the men's singles and doubles scores differently though they both agree on their outcome.
{{note label|Shields|i|i}} Frank Shields wasn't able to compete in the final of the Wimbledon Championships because of a twisted knee, which was injured in the ninth game of the fourth set of his semifinal match against Jean Borotra.
