"Mooo!" (often stylized in all caps) is a 2018 song by American singer and rapper Doja Cat. After originally being uploaded exclusively as a music video on August 10, 2018, it became a viral internet meme and amassed over 75 million views. It was consequently released as the first single off the deluxe edition (and third overall) of her debut studio album Amala. The viral success of "Mooo!" is considered to have been a major influence to Doja Cat's internet fame, ultimately "setting the tone for her career", despite being considered by Doja Cat herself as a "throwaway" and a "joke".
