Publius Valerius Poplicola was consul of the Roman Republic in 475 and 460 BC, and interrex in 462.
In his first consulship Valerius was assinged responsibiity for the war against Veii and the Sabines. The Roman army was reinforced by auxiliaries from the Latin allies and the Hernici.
The Sabine army was camped outside the walls of Veii. Valerius attacked the Sabine defences. The Sabines sallied forth from their camp, but the Romans had the better of the fighting, and took the gate of the Sabine camp. The forces of Veii then attacked from the city, but in some disorder, and a Roman cavalry charged routed the Veientes, giving Rome the overall victory.
Valerius was awarded a triumph for the victory, which he celebrated on 1 May.
In his second consulship he was killed recovering the capitol from Appius Herdonius.
He is said to be the son of Publius Valerius Publicola, the consul of 509, but according to another tradition, that son fell in battle at Lake Regillus; perhaps the consul of 475 was his grandson.
