Vonnie DeLong, formerly Vonnie Thompson and Vonnie Killmer (born October 17, 1965), is an American women's basketball coach and former player. She played college basketball at both Notre Dame and the University of Michigan. She holds the Michigan Wolverines women's basketball single-season record with 156 assists during the 1987–88 season.

DeLong is currently the head coach of the girls' basketball team at Saginaw Heritage High School. She previously served as a coach at Saginaw's Arthur Hill High School and Saginaw Valley State University. She was inducted into the Saginaw Valley Sports Hall of Fame in 2011.

Early years
DeLong was raised in Carrollton, Michigan, and attended Carrollton High School from 1979 to 1982. She was thrice selected as an All-State player and led Carrollton to three Michigan Class C state championships. She scored over 1,000 points in her high school career and was selected as a third-team All-American as a senior.

College basketball
DeLong enrolled at the University of Notre Dame and played for the Notre Dame Fighting Irish women's basketball team as a freshman. At the start of her sophomore year, she felt she was not given an opportunity to perform. In January 1986, she transferred to the University of Michigan in the middle of the basketball season, citing a lack of chemistry with the Notre Dame coaching staff.

DeLong, then known by her maiden name Vonnie Thompson, played two seasons at Michigan from 1986 to 1988. During her time at Michigan, she was five feet, seven inches tall. In her first year at Michigan, she led the team with 50 steals, averaged 36 minutes per game, and 7.3 points per game, and was named the team's co-MVP. During the 1986–87 season, she also broke Michigan's single-season record and led the Big Ten Conference with 147 assists.

During the 1987–88 season, DeLong broke her own single-season record with 156 assists. Michigan head coach Bud VanDeWege called her a "gym rat," which he described as "a player who likes to pick up a ball and play. It's someone who keeps playing during vacations or even after the season is over."

DeLong's annual assist totals still rank as the two highest single-season totals in program history. She also holds Michigan's single-game record with her total of 12 assists against Northeastern on December 5, 1987. Her two-year total of 303 assists ranks eighth on Michigan's list of career assist leaders. DeLong graduated from Michigan with a bachelor's degree in sports management and communications.

I miss just being involved in it."
