Eros, often known by his Roman name Cupid, is widely considered the most romantic god.
While Aphrodite, the Greek goddess of love, often gets the spotlight, it is her son Eros who truly embodies romantic love by bringing desire and attraction to humans. He is famously known for his golden arrows that incite love and his lead arrows that incite aversion, thereby controlling the ebb and flow of romantic feelings.
Therefore, Eros/Cupid is the most suitable answer to the question of the most romantic god.
