The sportsman, 42, lodged legal papers to end his union to Lhotse Merriam in a court in San Diego, California on Friday (04Feb11).
Hawk and Merriam wed in January 2006. They have a two-year-old daughter, called Kadence Clover.
In a joint statement, the former couple says, "We have made the difficult decision to file for divorce.
"We remain deeply committed and loving parents to our daughter, and out of respect for that responsibility we ask that people honour our family's privacy during this important time of transition. Thank you for your understanding."
Hawk also has three sons from his previous two marriages.
