Thomas Walker Rush (born February 8, 1941) is an American folk and blues singer, guitarist and songwriter who helped launch the careers of other singer-songwriters in the 1960s and has continued his own singing career for 60 years.

Rush was born in Portsmouth, New Hampshire, United States, the son of a teacher at St. Paul’s School, in Concord, New Hampshire. He began performing in 1961 while studying at Harvard University, after having graduated from the Groton School. He majored in English literature. His early recordings include Southern and Appalachian folk or old-time country songs, Woody Guthrie ballads, and acoustic-guitar blues, such as Jesse Fuller‘s “San Francisco Bay Blues,” which appeared on both of his first two LPs. He regularly performed at the Club 47 coffeehouse (now called Club Passim) in Cambridge, the Unicorn in Boston, and The Main Point in Bryn Mawr, Pennsylvania. In the 1970s he lived in Deering, New Hampshire.

Rush is credited by Rolling Stone magazine with ushering in the era of the singer-songwriter. In addition to performing his own compositions, he sang songs by Joni Mitchell, Jackson Browne, James Taylor, Murray McLauchlan, David Wiffen and William Hawkins, helping them to gain recognition early in their careers.

His 1968 composition “No Regrets” has become a standard, with numerous cover versions having been recorded (Rush did two radically different versions himself). These include The Walker Brothers, who gave Tom Rush Top Ten credit as a songwriter on the UK Singles Chart, Emmylou Harris, who included the song on her 1988 album Bluebird, and Midge Ure whose cover also made the UK Top Ten.
