Ayu Tsukimiya (月宮 あゆ, Tsukimiya Ayu^?) is a fictional character and the main heroine in Key's adult visual novel Kanon, followed closely by Nayuki Minase who is the only Kanon heroine to appear with Ayu on three of the official game covers released by Key. Ayu was created by Naoki Hisaya who wrote her scenario for the visual novel, and designed by Itaru Hinoue. Hisaya commented on how he thought Ayu was the one character in Kanon that he felt he grasped the best, but noted it was very difficult to write her character due to Ayu being primarily energetic. After Hinoue drew wings on Ayu's backpack, Hisaya suggested that they remove them due to spoiler reasons, and while Hinoue went along with it at the time, the wings were later included once again.

Yuichi Aizawa, the protagonist of Kanon, meets a lively seventeen-year-old Ayu on the day after he moves to the city depicted in the game. As the story progresses, Yuichi discovers that she is trying to find something she lost, but she cannot remember what it is; Yuichi tries to help her in her search, but with no initial success. One of her most defining characteristics is the repeated utterance of her catch phrase "ugū" (うぐぅ^?) which she mutters as an expression of various negative emotions such as frustration, anger, and fear. Her favorite food is taiyaki, and she is seen eating the confection many times throughout Kanon.
