Dionysios Solomos (Greek: Διονύσιος Σολωμός, 8 April 1798 - 9 February 1857) was a Greek poet from Zakynthos. He is best known for writing the Hymn to Liberty (Greek: Ὕμνος εἰς τὴν Ἐλευθερίαν), of which the first two stanzas on music by Nikolaos Mantzaros became the Greek national anthem in 1865.
He was the central figure of the Heptanese School of poetry, and is considered the national poet of Greece - not only because he wrote the national anthem, but also because he contributed to the preservation of earlier poetic tradition and highlighted its usefulness to modern literature. Other notable poems include Τhe Cretan (Ὁ Κρητικός), The Free Besieged (Ἐλεύθεροι Πολιορκημένοι) and others.
A characteristic of his work is that no poem except the Hymn to Liberty was completed, and almost nothing was published during his lifetime.
Ο «Ύμνος ενός την Ελευθερίαν» και οι «Ελεύθεροι Πολιορκημένοι» είναι αριστουργήματα της ελληνικής γλώσσας και του ελληνικού ήθους. Και μόνο για αυτά τα δυο ο Σολωμός αξίζει αιώνια δόξα.
Τα υπόλοιπα ποιήματα, σχέδια και αποσπάσματα, καθώς και οι σημειώσεις του Πολυλά, φωτίζουν πτυχές αυτού του απείρως ευαίσθητου ανθρώπου, αν και ίσως όχι με τον καλύτερο τρόπο λόγω της -δικαιολογημένης όπως εξηγείται- αποσπασματικότητας στο έργο του.
