Smile! :D (stylized in all caps) is the third studio album by American electronic music producer Porter Robinson, released on July 26, 2024, through Mom + Pop Music. In recording the album, Robinson sought to break away from many stylistic elements of his previous work. The music on the record draws from pop-punk, early 2000s rave, and hyperpop influences.

Four singles – "Cheerleader", "Knock Yourself Out XD", "Russian Roulette", and "Kitsune Maison Freestyle" – were released to promote the work. The album received generally favorable reviews, with critics praising its bold production and emotional depth, though some noted its chaotic structure. The album is being supported by a world tour from 2024 to 2025.
