There are two main events each year at Arpajon:
The Carnival of Bineau, in which a representation of the steward is burned in Châtres Square, takes place every year on the first Sunday of March.

The Foire aux haricots (The Bean Festival) started in 1922 and was recognised as a national fair in 1970.
It is a trade and crafts event which is held every third weekend in September over 4 days in memory of the market gardening that there was in the commune in the past.
The bean celebrated here is the chevrier.

There are other national events such as the Fête de la Musique (Festival of Music) which are celebrated in the commune.
