Year 332 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Calvinus and Arvina (or, less frequently, year 422 Ab urbe condita). The denomination 332 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.
- The Persian King Darius III twice sends Alexander letters of friendship. The second time he offers a large ransom for his family, the ceding of all of the Persian Empire west of the Euphrates River, and the hand of his daughter in return for an alliance. Alexander rejects both letters and marches into Mesopotamia.
- Alexander of Macedonia occupies Damascus and, after a siege lasting seven months, destroys Tyre during which there is great carnage and the sale of the women and children into slavery.
- Leaving Parmenion in Syria, Alexander advances south without opposition until he reaches Gaza where bitter resistance halts him for two months, and he sustains a serious shoulder wound during a sortie.
- Alexander conquers Egypt from the Persians. The Egyptians welcome him as their deliverer, and the Persian satrap Mazaces wisely surrenders. Alexander's conquest of Egypt completes his control of the whole eastern Mediterranean coast.
- Alexander spends the winter organising the administration of Egypt. He employs Egyptian governors, while keeping the army under a separate Macedonian command.
- Alexander founds the city of Alexandria near the western arm of the Nile on a site between the sea and Lake Mareotis, protected by the island of Pharos, and has the city laid out by the Rhodian architect Deinocrates.
- Chandragupta Maurya captures Magadha: Chandragupta, with the help Chanakya (Kautilya), who is also known as the Indian Machiavelli, destroyed the Nanda rulers of Magadha and established the Mauryan empire. It is said that Chanakya met Chandragupta in the Vindhya forest, after being insulted by the Nanda king.
- After a victory over the Samnites and Lucanians near Paestum, Alexander of Epirus makes a treaty with the Romans.
