Not in WI at an uncontrolled "T" intersection. I'd suspect most states are the same.
From WI statutes 346.18:
(3m) Uncontrolled “t" intersection. At an intersection where traffic is not controlled by an official traffic control device or by a traffic officer, the operator of a vehicle approaching the intersection on a highway which terminates at the intersection shall yield the right-of-way to any vehicle approaching the intersection on a highway which continues through the intersection.
