S.U.N.Y., Stonybrook, NY, 3/17/73 is an album by the country rock band the New Riders of the Purple Sage. It was recorded live on March 17, 1973, at Stony Brook University. It was released on November 13, 2007. It was the fifth complete New Riders concert that was recorded in the 1970s and released in the 2000s as an album on the Kufala Recordings label.

The New Riders performed two sets of music that night, as usual during that period. They played 29 songs, a combination of originals and covers. Folk singer Ramblin' Jack Elliot sat in with NRPS for their encore – the Rolling Stones tunes "Connection" and "Honky Tonk Women".

The photo of the band on the album cover, by Chuck Pulin, was taken on or about the date of the S.U.N.Y. show. Pictured from left to right are the "classic" early 1970s lineup — Dave Torbert, John "Marmaduke" Dawson, Spencer Dryden, David Nelson, and Buddy Cage.
