Daniel Baldwin's wife -- fresh on the receiving end of divorce papers -- was just arrested for a probation violation ... TMZ has learned.

Joanne Baldwin was busted in the Portland, Oregon area this afternoon.

We don't know what prompted the arrest ... but a booking sheet says she's being held for, "PROBATION VIOLATION DRIVING UNDER INFL OF INTOX."

Daniel got a restraining order against Joanne yesterday -- and in the documents he says Joanne has a serious drinking problem and prior DUIs.
