The Cry Baby Tour Diaries are a series of short videos that Melanie Martinez films while in each town that she has a concert in for the Cry Baby Tour. They're filmed in various places such as diners, hotels, while on the road, or backstage at concerts during meet & greets. Melanie uploads the diaries on her Tumblr. Each diary revolves around the theme of Melanie's debut album, Cry Baby, which is childhood themes paired with adult situations.
- There is someone wearing a wolf mask in some of the diaries, which could possibly be a reference to Tag, You're It and Milk and Cookies.
- Tom & Jerry recur in the diaries, and could have a possible esoteric meaning.
