Legendaddy (stylized in all caps) is the eighth studio album by Puerto Rican rapper Daddy Yankee, released on March 24, 2022, by El Cartel Records and Republic Records. It is his first and only album released directly under Universal, rather than its Latin division, after signing a global distribution deal in 2020.

Published 10 years after his previous studio album, Legendaddy was originally intended to be Daddy Yankee's last record, as he announced that he would retire from music after the end of his farewell concert tour, La Última Vuelta, in 2023. Nevertheless, he subsequently returned to music, releasing Lamento en Baile in 2025.

Daddy Yankee described its themes as "fight, party, war and romance." Musically, Legendaddy is primarily a reggaeton record that incorporates trap and elements of salsa, bachata, cumbia, dembow and electronic dance music. He co-wrote and co-produced all 19 tracks, for which he recruited producers including Play-N-Skillz, Dímelo Flow, Luny, Tainy, and Chris Jedi. It features collaborations with Bad Bunny, Becky G, El Alfa, Lil Jon, Michael Buffer, Myke Towers, Natti Natasha, Nile Rodgers, Rauw Alejandro, Pitbull, and Sech. The album received mostly positive reviews from music critics, who referred to it as a good send-off for his retirement, although some of its tracks were criticized. It was nominated for a Grammy Award for Best Música Urbana Album, while the single "Agua" garnered him a Latin Grammy Award for Song of the Year nomination.

Eight singles were released from the record, of which the Bad Bunny-featured "X Última Vez" peaked at number 23 on the Billboard Global 200 and within the top 10 in 10 Latin American countries, while "Remix" and "Rumbatón" reached number one in Daddy Yankee's native Puerto Rico; the former was the most-played radio song of the year in the country. Legendaddy became his highest-peaking album in Spain, at number two; the United States, at eight; Switzerland, at 17; and Canada, at 78. It subsequently received a Latin platinum and gold certification in the United States and Spain, respectively. Legendaddy is Daddy Yankee's final studio album in the reggaeton and hip-hop genre.

Following the release of Daddy Yankee's sixth studio album Prestige (2012) and his mixtape King Daddy (2013), it was announced in 2014 that his next project would be King Daddy II, which was later renamed El Disco Duro and scheduled to release in 2016. On October 26, 2016, he showed some of the album's tracks to Zumba creator Beto Pérez, with whom he had a partnership, and announced that it would be released during early 2017. On June 21, 2017, when asked about the record, he stated that the release had been postponed due to standalone singles being more profitable. In 2019, Vice contributor Gary Suarez opined that it was "either completely dead in the water or overdue for a radical revision from what he originally intended," while Ulises Fuente of La Razón anticipated that it might not be released because of the success of his standalone singles. In February 2020, Puerto Rican urban music news media Rapetón reported that Daddy Yankee's manager and label Pina Records' CEO, Raphy Pina, stated in a now-deleted post that "people [were] waiting for something that was never made".

On September 10, 2020, Daddy Yankee closed a global distribution deal with Universal Music Group with plans of releasing a new album and producing a documentary about the history of reggaeton. He had his music distributed by Universal through Capitol Latin since 2012 and proposed the recording of a new album due to him owing the label several singles. On September 15, 2021, Billboard's Leila Cobo stated that the then-unnamed album would release in the fall, while Daddy Yankee hinted at a retirement and said that he saw himself growing as an executive producer of movies and documentaries. On September 23, 2021, during his acceptance speech for his induction into the Billboard Latin Music Hall of Fame, Daddy Yankee told his fans to "enjoy his last musical round". Following that, on December 30, 2021, he posted that he was going to "give his last round to the world" in 2022.

On March 20, 2022, he posted a video on his social media in which he announced that he would retire from music after the conclusion of his upcoming farewell concert tour, La Última Vuelta, as well as the release date for his final album, Legendaddy. In the video, the rapper said that he "finally [saw] the finish line" and that he would "give [his fans] all the styles that have defined [him] in one single album," which he referred to as "his best production". The announcement was made on the 27th anniversary of Daddy Yankee's and his wife Mireddys Gonzalez's marriage; the latter posted that "[he] had enjoyed Daddy Yankee for a long time, but now is Raymond Ayala's turn to enjoy what he has built." The album's track list was posted on March 22, 2022, while the guest features were revealed a few hours before the release.

Daddy Yankee decided to retire in 2020 while working on the album during the COVID-19 pandemic and after realizing that he was "feeling good, pleased and accomplished" and that he had to "give himself the opportunity to enjoy everything he had achieved" after working non-stop for 32 years. He always wanted to retire young and felt that the time had come to "look for something beyond the industry" and to be a "normal person". He decided to feature a track list consisting entirely of new songs, without including previously released singles from past years, stating that "it would make an impression because it's something that isn't done anymore." He said that he will have music as a hobby, like he used to when young, and that he sees himself "owning more teams, producing content for movies, documentaries and series [and] producing new music acts." In February 2023, Daddy Yankee announced an "extension" for the album with pre-recorded bonus tracks, including "Chispa", which was selected as the 2023 World Baseball Classic anthem.
