The Roman goddess of crossroads, often identified with the Greek Hecate, was Trivia. The name comes from the Latin trivium, meaning a place where three roads meet, and it was chiefly an epithet of Diana rather than a wholly separate goddess in every tradition.
Roman poets used Trivia for Diana in her role as guardian of roads, three-way junctions, the night, and the boundary between the living world and the underworld. Virgil, Catullus, and Seneca all preserve this association. Crossroads were spiritually charged places in ancient Mediterranean religion because they represented movement, choice, danger, and transition.
Trivia was also linked with the moon and with the triple form of Diana, Luna, and Hecate. That overlap explains why modern summaries sometimes describe Trivia as Hecate herself, while ancient Roman usage more often treats the name as a title or aspect of Diana.
A common mix-up is Diana: she is the underlying Roman goddess, while Trivia is her crossroads epithet in this context.
