The Hlinka Gretzky Cup is an annual under-18 tournament held each August. The competition began in 1991 as the Phoenix Cup, and was renamed the Ivan Hlinka Memorial Cup in 2007 before becoming the Hlinka-Gretzky Cup in 2018.

All time, the U.S. Under-18 Men's Select Team has won the tournament once (2003), while earning second-place finishes in 2016, 2013, 2010, 2006, 2000, 1996, 1994 and 1993.

The 2021 tournament was played Aug. 2-7 in Piešťany, Slovakia & Břeclav, Czech Republic, with the U.S. competing alongside the Czech Republic, Finland, Germany, Russia, Slovakia, Sweden and Switzerland. 

The tournament will alternate between Alberta and the Czech Republic/Slovakia annually through 2022.
