R.R. Williams is the solo project of American songwriter, singer and musician Mike Williams from Tulsa, OK, United States. For his stage name, Williams adopted the initials of his father, Reginald Roy Williams, as a tribute to his memory.

Williams used to play in punk rock bands when he was younger, but fell in one with Americana / roots rock while playing in John Moreland's backing band. He released his début solo EP, The Going Stays Tough, in November 2020. A full-length solo album, entitled Unremarkable Lives, came out in August 2024.

Williams sings about "American life from the honest-to-God user end (...) Williams is a straight shooter, and with a poet's economy of language he dares to ask our most honest questions of the universe. Braiding together Heartland rock, poignant acoustic balladry, and country-tinged folk, he lays bare the urgent matters that haunt the dark and quiet moments: Purpose, Fate, Destiny, Redemption."
