The B9030 is a short B-road in north Aberdeenshire.
It starts on the A950 to the north of Old Deer and heads south into the village, crossing the former Aberdeen to Peterhead railway line (now a footpath) and the South Ugie Water en route. By the church in the village centre the road TOTSOs left, with the road ahead (or, more precisely, round to the right) being the B9029.
The South Ugie Water is followed out of Old Deer as far as the cemetery. The road remains flat, however, and soon reaches Stuartfield, where it runs through the main square in the village. On the far side of town the road bends to the right to cross a stream before climbing out of the valley. The remainder of the route continues southwestwards across undulating fields with the road finally descending into Auchnagatt. The road bends sharply to the left on the near side of the village and ends soon afterwards at a T-junction on the A948.
