The Dialogues
Thirty-six dialogues and thirteen letters have traditionally been ascribed to Plato, though modern scholarship doubts the authenticity of at least some of these. Plato's writings have been published in several fashions; this has led to several conventions regarding the naming and referencing of Plato's texts.
The usual system for making unique references to sections of the text by Plato derives from a 16th century edition of Plato's works by Henricus Stephanus. An overview of Plato's writings according to this system can be found in the Stephanus pagination article.
One tradition regarding the arrangement of Plato's texts is according to tetralogies. This scheme is ascribed by Diogenes Laertius to an ancient scholar and court astrologer to Tiberius named Thrasyllus.
In the list below, works by Plato are marked (1) if there is no consensus among scholars as to whether Plato is the author, and (2) if most scholars agree that Plato is not the author of the work. Unmarked works are assumed to have been written by Plato.
- I. Euthyphro, Apology (of Socrates), Crito, Phaedo
- II. Cratylus, Theaetetus, Sophist, Statesman
- III. Parmenides, Philebus, Symposium, Phaedrus
- IV. First Alcibiades (1), Second Alcibiades (2), Hipparchus (2), (Rival) Lovers (2)
- V. Theages (2), Charmides, Laches, Lysis
- VI. Euthydemus, Protagoras, Gorgias, Meno
- VII. (Greater) Hippias (major) (1), (Lesser) Hippias (minor), Ion, Menexenus
- VIII. Clitophon (1), Republic, Timaeus, Critias
- IX. Minos (2), Laws, Epinomis (2), Epistles (1).

The remaining works were transmitted under Plato's name, most of them already considered spurious in antiquity, and so were not included by Thrasyllus in his tetralogical arrangement. These works are labelled as Notheuomenoi ("spurious") or Apocrypha.
