This list includes all works that are generally agreed to be by Plato, and also some that, while disputed, are widely thought to be his. Dialogues whose authenticity is disputed are marked with an asterisk.

In line with the arguments of Chapter 2, Plato's works are here divided into three groups: Socratic dialogues, reflecting the thought of the historical Socrates; Platonic dialogues, reflecting Plato's thought during the period when he developed his most famous ideas; and later Platonic dialogues, reflecting Plato's thought in the last period of his life. The Socratic dialogues are often believed to have been written early in Plato's career, and to precede the Platonic dialogues, but this cannot be known with certainty.

Socratic dialogues

(In alphabetical order)

Alcibiades*

Apology

Charmides

Crito

Euthydemus

Euthyphro

Gorgias

Hippias Major*

Hippias Minor

Ion

Laches

Lysis

Meno

Protagoras

The Gorgias and Meno are often thought to have both Socratic and Platonic elements.

The Menexenus is also often grouped with the Socratic dialogues, though, being a satirical work, it does not directly reflect the thought of either Socrates or Plato.

Platonic dialogues

(In conjectural order of composition)

Cratylus

Phaedo

Symposium

Republic

Phaedrus

Parmenides

Theaetetus

The Parmenides and Theaetetus are widely thought to be the last of this group, and to have some features in common with the late group.

Later Platonic dialogues

(In conjectural order of composition)

Timaeus

Critias (incomplete)

Sophist

Statesman (also called Politicus)

Philebus

Laws

Epinomis*

The Seventh Letter, if genuine, also belongs to the last period of Plato's life.
