It was reported on April 28, 2016, that Ripken and his wife Kelly had divorced after a one-year separation.
In 2018, Ripken married Laura S. Kiessling, née Kaufman, an Anne Arundel County Circuit Court judge.
She took his last name.

His son Ryan is also a baseball player, and was drafted by the Orioles in the 20th round of Major League Baseball's 2012 amateur draft.
He chose to attend college instead, beginning his freshman year at the University of South Carolina in 2012.
He transferred to Indian River Community College and was drafted in the 15th round of the Major League Baseball's 2014 amateur draft by the Washington Nationals.
After being released by the Nationals in March 2017, he signed with the Orioles and was assigned to the Aberdeen Ironbirds, which were owned by his father and played at a stadium that carries the family name.
Ryan advanced to the Delmarva Shorebirds in 2018 and the Frederick Keys in 2019.

Ripken's mother, Violet Ripken, was kidnapped at gunpoint and safely returned on July 24, 2012.
She was gone for 12 hours before her disappearance was reported to authorities.
On October 15, 2013, she was approached by a man with a handgun in a parking lot at the NBRS Bank in Aberdeen, Maryland.
The man demanded her car, but he fled after she activated a key alarm.
She was unharmed.
A spokesman for the Aberdeen Police said the two incidents appeared unrelated.

Ripken has written nearly thirty books.
After the 1996 season, he released an autobiography titled The Only Way I Know, co-written with Mike Bryan, which was a New York Times Best Seller.
Following his retirement, he wrote several more, including Play Baseball the Ripken Way: The Complete Illustrated Guide to the Fundamentals, also written by his brother Billy and co-authored by Larry Burke, in 2005.
He released the book Parenting Young Athletes the Ripken Way, co-written with Rick Wolff, in 2006 after seeing too many young athletes who he felt were being pressured unnecessarily by their parents.
He said, "I was thinking, 'This just creates too much pressure on kids.'
They need to find an environment in which they can explore their game ... without all these kinds of pressures being brought to bear.
Once I started thinking about it, I saw we had more than enough to fill a book."
Then in 2007, he released three books, starting with Coaching Youth Baseball the Ripken Way, also written by his brother Billy and co-authored by Scott Lowe, which highlights 50 practice drills, topics include coaching responsibly, goal setting for youth, and effective practice planning.
Later, in April of that year, he released two more books: Get in the Game: 8 Elements of Perseverance That Make the Difference, co-written with Donald T. Phillips, described as a motivational guide to success; and The Longest Season, co-written with Ron Mazellan, a children's book about the Orioles' 1988 season.
In 2011, he released Hothead, a children's fiction book co-written with Kevin Cowherd which was also a New York Times bestseller.
In addition, he has been writing a weekly youth sports advice newspaper column in the Baltimore Sun since 2005.

In addition to his writing, Ripken has been the subject of several books.
In 1995, Harvey Rosenfeld released a biography on him entitled Iron Man: The Cal Ripken Jr., Story.
Later, in 2007, Jeff Seidel released a biography on him entitled, Iron Man: Cal Ripken Jr., a Tribute.
A children's biography of Ripken, Cal Ripken Jr., Quiet Hero was published in 1993 by Lois Nicholson.
