Year 134 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Aemilianus and Flaccus (or, less frequently, year 620 Ab urbe condita). The denomination 134 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.
- Scipio Aemilianus, victor of Carthage, takes command in Spain against the Numantians. He recruits 20,000 men and 40,000 allies, including Numidian cavalry under Jugurtha. Scipio, an expert in sieges, builds a ring of seven forts and a ditch palisade before beginning the Siege of Numantia. The perimeter of the circumvallations is twice as long as that of the city. The river Durius (Douro), enables the defenders to be supplied by small boats.
- Caius Fulvius Flaccus, as consul, is sent against the slaves. Uprising of 4,000 slaves crushed at Sinuessa, in Campania. Slave uprisings repressed in Attic silver mines and on the island of Delos.
- John Hyrcanus becomes high priest and prince (ruler) of Judea, until 104 BC, following the murder of his father Simon Maccabaeus by Ptolemy the son of Abubus in 135 BC.
