Jonathan Rey Bornstein (born November 7, 1984) is an American former professional soccer player who plays as a left-back.

In 2002, Bornstein was California Collegiate Athletic Association (CCAA) Freshman of the Year, first-team All-CCAA, and second-team All-Far West Region, as he led the team in scoring.

[3] In 2003, he was again first-team All-CCAA and second-team All-Far West Region, and was selected to the College Sports Information Directors of America (CoSIDA) Academic All-America College Division District VIII team with a 3.30 GPA in Business Administration, as he led Cal Poly in all scoring categories.

[3] Bornstein was a teammate of Benny Feilhaber at the youth (with the Irvine Strikers), college (at UCLA, where they were roommates), and national-team level, and at the Maccabiah Games in Israel.

[6] A forward in college, he was converted to a left back by Chivas coach Bob Bradley, and was his team's surprising starter at the position when the season opened.

[7] Injuries and suspensions forced Bornstein back into an attacking role for Chivas USA's June 3 match against FC Dallas, where the rookie scored his first MLS goal.

He continued his fine play in the back and also contributed to the attack during the rest of the season, finishing the year with four assists and six goals, leading all rookies.

When he came back, Chivas coach Preki began to employ him in an attacking capacity, which Bornstein trained for in his youth.

[10] News stories claimed that the offer involved a transfer fee of $750,000 and would increase the player's salary five-fold to around $500,000 a season.

[6] In July 2010, it was announced by Chivas USA that Bornstein would join Tigres de la UANL in January 2011, following the conclusion of the 2010 Major League Soccer season.

[14] On February 13, 2013, Portland traded Bornstein's MLS rights back to Chivas USA with allocation money for midfielder Ben Zemanski.

He started the group stage matches at the 2009 FIFA Confederations Cup, but was relegated back to the bench when Carlos Bocanegra returned from injury.

He scored the equalizing goal in the United States' final World Cup qualifier against Costa Rica in the fifth minute of injury time.

The goal meant that Honduras, when combined with their win over El Salvador, a game in which Bornstein captained the US side, qualified automatically for the 2010 World Cup.

Bornstein played in the 2005 Maccabiah Games, in Israel, representing the U.S. along with Benny Feilhaber, Kevin Friedland, Matt Reiswerg, and Leo Krupnik, winning a silver medal.

[31] His father is Jeff Bornstein, who is Jewish and was born in Torrance into an Orthodox family, and worked for Hostess until his death in 2014.

[27] His step-mother, Rochelle Bornstein, works as a deli supervisor and cashier at a grocery store in Long Beach, California.
