The passé simple (French pronunciation: [pase sɛ̃pl], simple past, preterite, or past historic), also called the passé défini (IPA: [pase defini], definite past), is the literary equivalent of the passé composé in the French language, used predominantly in formal writing (including history and literature) and formal speech. As with other preterites, it is used when the action has a definite beginning and end and has already been completed. In writing it is most often used for narration.

Even though the passé simple is a common French verb tense, used even in books for very young French children, it is usually not taught to foreigners until advanced French classes. The passé simple is most often formed by dropping the last two letters of the infinitive form of the verb and adding the appropriate ending.

The three main classes of French regular verbs (-er, -ir, -re) are conjugated in the passé simple tense in the following way:

Several common irregular verbs:

Many other irregular verbs are easily recognized because the passé simple often resembles the past participle. For example, il courut (he ran) is from courir, for which the past participle is couru. Some, however, are totally irregular. Naitre (to be born) has a past participle né and yet the passé simple is (for example) je naquis (I was born).

The passé simple is used to express:
