Group D was one of eight groups in the 2025 FIFA Club World Cup, an international club soccer tournament hosted in the United States and organized by FIFA. It comprised four teams: Flamengo of Brazil; Espérance de Tunis of Tunisia; Chelsea of England; and Los Angeles 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 was the first in the tournament's history to be played under its quadrennial format with 32 teams. The group's matches began on June 16 and concluded on June 24.

The 32 participants were divided into four pots based on their confederation and ranking within FIFA's club ranking system. Each of the eight groups would receive one team from each pot. Teams from the same confederation could not be drawn into the same group except for those from UEFA, which had twelve slots; teams from the same national association were not able to be drawn into the same group.
