During the event in the Polish capital on Thursday, athletes pledged to compete fairly and with sportsmanship ahead of their departure for Paris, news outlets reported.
The group included track-and-field contestants, cyclists, wrestlers and canoers, Polish state news agency PAP reported.
Sports Minister Sławomir Nitras, Polish Olympic Committee head Radosław Piesiewicz, and the French ambassador to Warsaw, Étienne de Poncins, congratulated the athletes on making the Olympic team and wished them success in Paris.
The rest of the Polish team will take their Olympic oaths on July 22 and 23, the Polish Olympic Committee said.
A total of 213 Polish athletes, 100 men and 113 women, have been selected to compete in the Paris Games, which take place from July 26 to August 11.
Poland will be represented by athletes competing in multiple Olympic sports, including 65 track-and-field contestants and 20 swimmers.
Three-time Olympic hammer champion Anita Włodarczyk and 3x3 basketball player Przemysław Zamojski have been named as the flag bearers for the Polish delegation at the opening ceremony of the Games.
The first group of Polish athletes is expected to arrive in the French capital on Friday.
