Caroline Wozniacki won her first major title at the Australian Open by defeating Simona Halep in the final, returning to the world No. 1 ranking for the first time since 2012. Halep then went on to win her first major at the French Open on her fourth appearance in a major final, defeating Sloane Stephens in three sets. Angelique Kerber won her third major singles title at Wimbledon, defeating Serena Williams in the final and becoming the first German since Steffi Graf in 1996 to lift the trophy. Naomi Osaka won her first major title at the US Open, defeating Serena Williams in the final. At the age of 20, Osaka became the first Japanese woman to win a major singles title and the youngest US Open champion since Maria Sharapova in 2006.

These tables present the number of singles (S), doubles (D), and mixed doubles (X) titles won by each player and each nation during the season, within all the tournament categories of the 2018 WTA Tour: the Grand Slam tournaments, the year-end championships (the WTA Tour Championships and the WTA Elite Trophy), the WTA Premier tournaments (Premier Mandatory, Premier 5, and regular Premier), and the WTA International tournaments. The players/nations are sorted by:

• total number of titles (a doubles title won by two players representing the same nation counts as only one win for the nation);
• cumulated importance of those titles (one Grand Slam win equalling two Premier Mandatory/Premier 5 wins, one year-end championships win equalling one-and-a-half Premier Mandatory/Premier 5 win, one Premier Mandatory/Premier 5 win equalling two Premier wins, one Premier win equalling two International wins);
• a singles > doubles > mixed doubles hierarchy;
• alphabetical order (by family names for players).
