With 164 victories during the 1990s, Glavine earned the second highest number of wins as a pitcher in the National League, second only to teammate Greg Maddux's 176.

In 2005, along with several Mets teammates, Glavine served as a spokesman for Volunteers of America's "Operation Backpack" program.

In 2007, Glavine supported the Rally Foundation through the Money in the Mitt 300 Challenge to support childhood cancer care by selling Vineyard Vines Rally Ties to commemorate his historic 300th win in an effort to raise $300,000. 300 signed ties were to be sold for $1,000 each.  In 2008, Glavine released a charity wine called "Cabernet Glavingnon" to raise funds for CURE Childhood Cancer, an organization founded to help conquer childhood cancer through research, education and support of patients and their families. Since 1992, Glavine has partnered with the Georgia Transplant Foundation to host the annual "Spring training" event, raising more than 4.3 million dollars for transplant candidates, recipients, and their families, in the state of Georgia  In 2011, Glavine became a color commentator for Atlanta Braves baseball games.  Glavine and his wife Christine have five children. One of their sons, Peyton, was selected in the 2017 MLB draft and is committed to attend Auburn University on a baseball scholarship. They live in Johns Creek, Georgia, and Glavine coaches his sons' baseball and hockey teams. Glavine is a Roman Catholic and has done a recorded piece for Catholic Athletes for Christ.  Glavine is known for being humble about his accomplishments and an avid golfer, so a good friend, Jack Kennedy, gifted Glavine six dozen golf balls that display his uniform number, 47, on one side and the number of losses he had in his career on the other, 203. The gift was given around the time Glavine received the phone call that he would be a first-ballot Hall of Fame inductee.
