The Jamies were an American singing group, led by Tom and Serena Jameson. The group's 1958 single for Epic Records, "Summertime, Summertime", reached #26 on the US Billboard Hot 100.

Both "Summertime" and its b-side, "Searching for You", are often described as doo-wop, because of their time period and their a cappella harmonies (with a harpsichord backing on "Summertime, Summertime"). However, both songs may also be described as pop versions of Sacred Harp styles, as the group started as church singers
