Assign account owner based on another field value

[MSVRad]

What is the best way to default an account owner (standard lookup field) to a certain person based on a value in a custom field?

Workflow rules would do it. The trigger being the custom field value and the action being a field update for the account owner.

So pretty much what I am trying to do is update the account owner field based on the billingstate field, I made the mistake of saying billingstate is a custom field, but it is actually a standard field.  Can I still do this with a workflow. If it is indeed possible, how would set my rule criteria, based on fields or based on a formula?

Create new workflow rule.
Select object: account

Rule criteria:

Field = Billing State/Province
Operator = equals
Value = whichever state/s you want assigned to this particular owner

Field to Update: Account Owner
Account Owner: select the owner for this state here.

Then just duplicate this rule for each owners territory.
