Chastain, whose game-winning penalty kick gave the USA the 1999 Women's
World Cup title, played 192 matches and scored 30 goals for the USA in an international career that ended in 2004. Chastain, a first-ballot Hall of Fame inductee, also won two Olympic gold medals
(1996 and 2004).
"To be inducted into the Hall of Fame and have my name read in the same sentence with our country's best is truly humbling," said Chastain.
MacMillan, a 1999 FIFA Women's World Cup champion and 1996 Olympic gold medalist, had a 12-year international career, playing in 176 matches. Her 60 career goals are currently ninth all-time in U.S. women's history.
"Playing for the USA was always an honor and privilege for me, and that could only be topped by being selected for the Hall of Fame," said MacMillan.
Garber enters the Hall of Fame on the Builder Ballot after 17 years as MLS commissioner.
"Thanks to the commitment and hard work of many people, our sport has grown significantly during the last few decades and there is no doubt the United States is a true soccer nation," said Garber. "It is an honor to be inducted alongside Brandi Chastain and Shannon MacMillan, two iconic figures in U.S. Soccer history who have impacted the sport at so many levels."
He also noted that FC Dallas, an original member of MLS, and Toyota Stadium, the league's third soccer-specific stadium, will serve as the new home of the National Soccer Hall of Fame. Groundbreaking took place on Thursday in Frisco, where the Class of 2016 was announce.
Details about this year's induction ceremony will be released at a later date.
