2025 FIFA Club World Cup Group B

Group B is one of eight groups in the 2025 FIFA Club World Cup, an international club soccer tournament organized by FIFA. It comprises four teams: Paris Saint-Germain of France; Atlético Madrid of Spain; Botafogo of Brazil; and Seattle Sounders FC of the United States. Teams qualified by winning the respective continental club championships of their confederation or through a ranking of their performance in competitions. Only two clubs per country were allowed to qualify unless three or four won their respective continental club championship. The 2025 edition of the FIFA Club World Cup is the first in the tournament's history to be played under its quadrennial format with 32 teams.

The tournament is being hosted by the United States and all matches in Group B will be played at two West Coast venues—Lumen Field in Seattle, Washington; and the Rose Bowl in Pasadena, California, near Los Angeles. A temporary grass pitch will be installed at Lumen Field for the tournament instead of using the stadium's normal artificial turf. The Sounders were automatically placed in Group B during the tournament draw due to their status as a host team. Following the draw in December 2024, Group B was labeled the tournament's "group of death" due to the strength of the teams. The group's matches began on June 15 and conclude on June 23.
