Year 476 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Rutilus and Structus (or, less frequently, year 278 Ab urbe condita). The denomination 476 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.
- Convicted in Sparta on the charge of accepting a bribe from the Aleudae family whilst leading an expedition to Thessaly against the family for their collaboration with the Persians, the Spartan King Leotychidas flees to the temple of Athena Alea in Tegea, Arcadia. A sentence of exile is passed upon him; his house is razed, and his grandson, Archidamus II, ascends the Spartan throne in his place.
- Cimon of Athens increases his power at the expense of Themistocles. He ousts Pausanias and the Spartans from the area around the Bosporus. The Spartans, hearing that Pausanias is intriguing with the Persians, recall him and he is "disciplined".
- Under the leadership of Kimon, the Delian League continues to fight the Persians and to release the Ionian cities from Persian domination. The capture of Eion on the Strymon from the Persians is led by Cimon.
- The Greek poet Pindar visits Sicily and is made welcome at the courts of Theron of Acragas and Hieron I of Syracuse. They commission some of his greatest poetry. It is through these connections that Pindar's reputation spreads all over the Greek world.
