Calendar year
 
Year 290 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Rufinus and Dentatus (or, less frequently, year 464 "Ab urbe condita"). The denomination 290 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

* Lucius Postumius Megellus, a consul from the previous year, is publicly tried for having used his office to have 2000 of his soldiers work on his farm. He is condemned by all the tribes and fined 50,000 denarii.
* The consuls Manius Curius Dentatus and Publius Cornelius Rufinus invade Samnium and defeat the Samnites in several engagements. The Samnites sue for peace, thus ending the Third Samnite War. The Samnites are recognised by the Romans as autonomous allies but are subordinate to Rome and must give up land as compensation.
* Curius subjugates the Sabines, possibly for their actions or inaction during the Third Samnite War. Their territory is annexed, securing direct Roman access to the Adriatic. The Sabines are granted civitas sine suffragio ("citizenship without the right to vote").
* Rome founds the colonies of Castrum, Sena and Adria.
