Johnson joins LSU teammate Seimone Augustus on the 12-member squad, which is comprised of the nation's top collegiate players.
The team will train July 7-24 in Colorado Springs, Colo., New York and Boston before competing in the inaugural FIBA World Championship for Young Women in Sibenik, Croatia, July 25 - Aug. 3.
Johnson, a 5-foot-3 point guard from New Orleans, averaged 20.0 points and 5.9 rebounds per game last season for the 30-4 Lady Tigers.
"Temeka played well during the trials and she is very deserving of being added to the team," LSU coach Sue Gunter said. "Having two LSU players on the 12-member squad makes a great statement about our team here at LSU. It's always an honor to be able to represent the United States in international competition and I'm proud that Seimone and Temeka are getting that opportunity."
Johnson will take the place of Southern Cal's Ebony Hoffman.
Other members of the squad include Duke's Alana Beard, UC Santa Barbara's Kristen Mann, Ohio State's Caity Matter, Kansas State's Nicole Ohlde, Arizona's Shawntinice Polk, Rutgers' Cappie Pondexter, Georgia's Christi Thomas, Kansas State's Kendra Wecker, Minnesota's Lindsay Whalen and Penn State's Tanisha Wright.
The team comprised of players 21-years-old of younger is coached by Ohio State head coach Jim Foster.
