William Owen Bradley (October 21, 1915 – January 7, 1998) was an American musician, bandleader and record producer who, along with Chet Atkins, Bob Ferguson, Bill Porter, and Don Law, was a chief architect of the 1950s and 60s Nashville sound in country music and rockabilly.

Bradley started with piano at a young age, and began performing professionally as a teenager. At age 20, he joined WSM (AM) as an arranger and musician, and by 1942 had become the station's musical director. At the same time, Bradley led a dance band that enjoyed popularity in local society circles.

In 1947, Bradley was hired by the head of Decca Records' country music division, Paul Cohen, to assist with recording sessions and later establish the label's operations in Nashville. In 1954, Bradley established Bradley Studios, later commonly known as the Quonset Hut Studio, which was the first music industry-related business in what is now known as Music Row, and helping establish Nashville as a recording industry center.

In 1958, Bradley became vice president of Decca's Nashville division. This period marked the beginning of the Nashville sound, a movement that aimed to broaden country music's appeal by incorporating pop elements. Bradley's work extended to producing records for artists like Patsy Cline and Loretta Lynn, playing a key role in their career successes.

Bradley sold Bradley Studios to Columbia Records in 1962, and two years later established Bradley's Barn, a new recording studio that continued to attract a range of recording artists. He was inducted into the Country Music Hall of Fame in 1974, reflecting his impact on the industry. Bradley's later years saw him working on selected projects, including k.d. lang's Shadowland album.

Bradley's contributions have been recognized with various honors, including the dedication of a public park and a bronze likeness in Nashville. His legacy in the music industry is marked by his role in shaping the Nashville sound and influence on several generations of musicians.
