Thymin (T, Thy, 5-Methyluracil) ist eine der vier Nukleinbasen in der DNA, zusammen mit Adenin, Cytosin und Guanin. In der RNA steht an seiner Stelle Uracil. Es ist eine heterocyclische organische Verbindung mit einem Pyrimidingrundgerüst und drei Substituenten (Sauerstoffatome an den Positionen 2 und 4, Methylgruppe an Position 5). Die Nukleoside von Thymin sind das Desoxythymidin in der DNA und das seltene Ribothymidin in der RNA (z. B. in der tRNA). In der Watson-Crick-Basenpaarung bildet es zwei Wasserstoffbrücken mit Adenin.
