The couple were married for 24 years and are the parents of twin 10-year-old sons. Crowe and Wilson separated in June 2008 and Wilson cited "irreconcilable differences" as the reason for the split when she filed for divorce in September.
UsMagazine.com said their divorce was finalized Wednesday in Los Angeles.
Crowe's film credits include "Jerry Maguire," "Say Anything" and "Almost Famous."
Wilson is best known for performing with her sister Ann as part of the rock band Heart.
