Arthur Horace James was an American lawyer, politician, and judge. A Republican, he served as the 14th lieutenant governor (1927–1931) and the 31st governor (1939–1943) of Pennsylvania.

The lieutenant governor is a constitutional officer of the Commonwealth of Pennsylvania. The lieutenant governor is elected for a four-year term in the same year as the governor. Each party picks a candidate for lieutenant governor independently of the gubernatorial primary. The winners of the party primaries are then teamed together as a single ticket for the fall general election. The lieutenant governor presides in the Pennsylvania State Senate and is first in the line of succession to the governor; in the event the governor dies, resigns, or otherwise leaves office, the lieutenant governor becomes governor. The Lieutenant Governor casts tie breaking votes in the State Senate.
