Benjamin Hammond Haggerty (born June 19, 1983), better known by his stage name Macklemore ( MAK-lə-mor; formerly Professor Macklemore), is an American rapper. A native of Seattle, Washington, he started his career in 2000 as an independent artist releasing: Open Your Eyes (2000), The Language of My World (2005), and The Unplanned Mixtape (2009). He rose to international success collaborating with producer Ryan Lewis as the duo Macklemore & Ryan Lewis (2009–2016).

Macklemore's and Lewis's single "Thrift Shop" (featuring Wanz) reached number one on the U.S. Billboard Hot 100 in 2013. The single was dubbed by Billboard as the first song since 1994 to top the Hot 100 chart without the support of a major record label; however Macklemore, in a slightly unusual recording contract, pays a nominal percentage of sales to use Warner Bros. Records's radio promotion department to push his singles. Their second single, "Can't Hold Us", also peaked at number one on the Hot 100 chart, making Macklemore and Lewis the first duo in the chart's history to have their first two singles both reach the peak position. Their debut studio album The Heist was released on October 9, 2012, and charted at number 2 on the U.S. Billboard 200. The duo won four Grammy Awards at the 2014 ceremony, including Best New Artist, Best Rap Album (The Heist), Best Rap Song and Best Rap Performance ("Thrift Shop"). The pair's second album, This Unruly Mess I've Made, was released on February 26, 2016.

In June 2017, Macklemore released "Glorious", a single featuring Skylar Grey, which marked his return to the music industry as well as his first major single produced without Lewis since his mainstream breakthrough. Macklemore released a second solo studio album, Gemini, in September of that year. On February 24, 2023, he released a follow-up album entitled Ben.
