Sport plays a significant part in the life of many Czechs who are generally loyal supporters of their favourite teams or individuals.

The two leading sports in the Czech Republic are football and ice hockey, both drawing the largest attention of both the media and supporters. The many other sports with professional leagues and structures include basketball, volleyball, team handball, Czech handball, athletics, floorball and others. Sport is a source of strong waves of patriotism, usually rising several days or weeks before an event and sinking several days after.

The events considered the most important by Czech fans are: the Ice Hockey World Championship, the Olympic ice hockey tournament, the European football championship, the football World Cup and qualification matches for such events. In general, any international match involving the Czech ice hockey or football national team draws attention, especially when played against a traditional rival: Germany in football; Russia, Finland, Sweden and Canada in ice hockey; and Slovakia in both.

Both summer and winter Olympic games are also very popular.
