Robert Clark Seger ( SEE-gər; born May 6, 1945) is a retired American singer, songwriter, and musician. As a locally successful Detroit-area artist, he performed and recorded as Bob Seger and the Last Heard and the Bob Seger System throughout the 1960s, breaking through with his first album, Ramblin' Gamblin' Man (which contained his first national hit of the same name) in 1969. By the early 1970s, he had dropped the 'System' from his recordings and continued to strive for broader success with various other bands. In 1973, he put together the Silver Bullet Band, with a group of Detroit-area musicians, with whom he became most successful on the national level with the album Live Bullet (1976), recorded live with the Silver Bullet Band in 1975 at Cobo Hall in Detroit, Michigan. In 1976, he achieved a national breakout with the studio album Night Moves. On his studio albums, he also worked extensively with the Alabama-based Muscle Shoals Rhythm Section, which appeared on several of Seger's best-selling singles and albums.

A roots rocker with a classic raspy, powerful voice, Seger wrote and recorded songs that dealt with love, women, and blue-collar themes, and is one of the best-known examples of a heartland rock artist. He has recorded many hits, including "Night Moves", "Turn the Page", "Mainstreet", "Still the Same", "Hollywood Nights", "Against the Wind", "You'll Accomp'ny Me", "Shame on the Moon", "Roll Me Away", "Like a Rock", and "Shakedown", the last of which was written for the 1987 film Beverly Hills Cop II and topped the Billboard Hot 100 chart. He also co-wrote the Eagles' number-one hit "Heartache Tonight", and his recording of "Old Time Rock and Roll" was named one of the Songs of the Century in 2001.

With a career spanning six decades, Seger has sold more than 75 million records worldwide, making him one of the world's best-selling artists of all time. Seger was inducted into the Rock and Roll Hall of Fame in 2004 and the Songwriters Hall of Fame in 2012. Seger was named Billboard's 2015 Legend of Live honoree at the 12th annual Billboard Touring Conference & Awards, held November 18–19 at the Roosevelt Hotel in New York. His farewell tour took place in 2018 and 2019.
