Kristin Lynne Haynie (born June 17, 1983) is an American former basketball player in the Women's National Basketball Association (WNBA) and current head coach for the Central Michigan women's team.
 Haynie was raised in Mason, Michigan. In high school, she played on the varsity team since her freshman year, and graduated from Mason High School in 2001.
 Haynie was the starting point guard for the Michigan State University Spartans all four years. She was instrumental in their 2005 Big Ten Championship and first ever trip to the Final 4. During her senior year, the Michigan State Women's Basketball Team had an excellent season, capturing 33 wins (including beating powerhouse programs like UConn, Tennessee and Notre Dame). Michigan State finally fell to Baylor University in the National Championship game. Haynie is frequently mentioned in the Michigan State Women's Basketball Record Book. One of her most impressive accomplishments was being the first and only woman (until 2017) to complete a triple double (points, assists and steals) in the NCAA tournament.
