The aim of this paper is to determine the indicators of the situational efficiency of the Croatian national handball team at the 2021 World Cup, played in Egypt. The previous format of this competition contained 24 national teams, but this year in Egypt we saw for the first time an expanded format of 32 teams that were divided into eight groups of four. The sample of entity consists of 21 national team members (3 goalkeepers + 18 players). In this paper, the efficiency of each individual player and the efficiency associated with their playing positions are determined. In the attack phase, six situational efficiency variables were analyzed; shooting from outside positions, wing positions and line position, as well as from breakthroughs, counterattacks and 7-meter throws. The goalkeepers performance is analyzed by the successful and unsuccessful saves of the opponents' shots directed towards the goal. In this championship, the Croatian national handball team sent a total of 263 shots towards the opponent's goal and scored 156 goals, which gives a success rate of 59%. Most goals were scored from the pivot position (44/61), then from the backcourt positions (34/92) and from the position of the wings (24/40). Followed by goals from counterattack (20/25) and breakthroughs (18/23), while the fewest goals were scored from the seven-meter line (16/22). The most efficient player of the Croatian national handball team at this championship was the circle runner Marino Marić with 26 goals from 33 attempts (79%). The first goalkeeper of the national team, Ivan Pešić, saved 44 out of 133 shots which gives a success rate of 33%. The Croatian national team played six games in this championship and achieved the result of three wins, one draw and two defeats, which ultimately brought them 15th place. One of the main reasons for failure this year were problems with injuries of some of the key players of the national team and generally very poor efficiency of backcourt strikers.
