Cry Baby is the debut studio album by American singer and songwriter Melanie Martinez, released on August 14, 2015, through Atlantic Records. Between September and December 2012, Martinez rose to prominence upon participating in the third season of the American edition of The Voice. After the show's completion, the singer began working independently on original material, which she says she spent the majority of 2013 writing.

The album was supported by the release of three singles. "Pity Party", was released on June 2, 2015, and, "Soap", was released on July 10, 2015. The third and final single, "Sippy Cup" was released July 31, 2015. Cry Baby is a visual concept album about a character named Cry Baby, who is a fantasy version of Martinez.

Musically, Cry Baby is primarily an alternative pop, electropop, and indie pop record, and received generally positive reviews from critics. In the United States, the album was certified double-platinum by the Recording Industry Association of America, after earning 2 million album-equivalent units (sales, streaming, and track sales). In 2020, the song "Play Date", went viral on video-sharing platform TikTok, causing the album to re-enter charts globally.
