Robin and Linda Williams are a husband-and-wife singer-songwriter folk music duo from Virginia. They began their musical association in Nashville, TN in 1971, performing in local clubs.

The Williamses first appeared on Garrison Keillor's A Prairie Home Companion radio show in 1976, gaining them national exposure as the show's audience expanded. They also toured and recorded with Keillor's group, the Hopeful Gospel Quartet. In the summer of 1993 they toured with Mary Chapin Carpenter and later sang on Carpenter's Grammy Award-winning album Stones in the Road. Their 1996 album, Sugar for Sugar, spent 11 weeks in the Top 20 of Gavin's Americana Chart. In 2004, they switched labels, recording Deeper Waters as their first release on Red House Records.

They appeared in the film A Prairie Home Companion, and are frequent guests on the radio show of the same name. In their appearance on show number 468 (2008-01-21) of the WoodSongs Old-Time Radio Hour, they discuss the film and program with host Michael Johnathon.
