Based on Greek Mythology, Aphrodite is widely considered the most beautiful female god.
Aphrodite's reputation as the goddess of beauty solidified after a beauty contest held amongst the gods on Mount Olympus. She was chosen as the most beautiful, confirming her place in mythology as the epitome of divine beauty. This perception has persisted through art, literature, and cultural references throughout history.
While various cultures have goddesses associated with beauty, Aphrodite's story and recognition give her a prominent position when directly answering the question.
