More than 60 accidents have killed or injured all or part of a sports team, in team-related circumstances that often receive widespread publicity. This list is organized into two sortable tables, summarizing aviation accidents and non-aviation accidents. The list does not attempt to include non-accidents (e.g. injuries while practicing their sport or targeted violent attacks), or non-team circumstances (i.e. athletes or sports personnel who experienced individual accidents).

The deadliest known accident for a single team was a November 1970 plane crash in West Virginia, whose fatalities included 37 members and 5 coaches of the Marshall University football team. Aviation accidents involving sports teams have decreased substantially since peaking in the 1970s, in parallel with peacetime aviation accidents overall. Serious non-aviation team accidents have most commonly involved buses, but also other modes of transportation and non-transport factors.

In response to team accidents, several sports leagues have established procedures for a "disaster draft", a contingency plan for rebuilding a team if many players are killed or disabled. The Kontinental Hockey League implemented such a plan in 2011 when the Lokomotiv Yaroslavl plane crash in Russia killed 26 players and 3 coaches.
