好运神（英语：Bonus Eventus）古罗马神话职司农业的神祇之一。其事迹反映于古典作家之著述，亦出现于古罗马硬币等相关文物中，具有重要地影响与积极意义。

Bonus Eventus ("Good Outcome") was a divine personification in ancient Roman religion. The Late Republican scholar Varro lists him as one of the twelve deities who presided over agriculture, paired with Lympha, the goddess who influenced the water supply. The original function of Bonus Eventus may have been agricultural, but during the Imperial era, he represents a more general concept of success and was among the numerous abstractions who appeared as icons on Roman coins.
