Clint Eastwood -- That's a Wrap ... on 18 Year Marriage

Clint Eastwood is officially a single man ... his divorce from wife Dina is final.

According to docs filed in Monterey County Superior Court, the marriage of Clint and Dina ended Monday. The couple struck a property settlement and custody agreement, but details are thin.

As TMZ previously reported, Clint attempted to block Dina from getting spousal support ... claiming money to which she was entitled was covered by their prenup. It's unclear if the terms of the prenup were honored in the settlement, but typically there's give and take in these divorce agreements.

Dina requested primary physical custody of their daughter, but she's 18 now so the issue is moot.

The couple separated in June 2012 and Dina filed for divorce last December.
