Bard College at Simon's Rock (more commonly known as Simon's Rock) is a private liberal arts college in Barrytown, New York. It is part of Bard College in Annandale-on-Hudson, New York.

Throughout its short history, the college has gone through names such as Simon's Rock, Simon's Rock Early College, Simon's Rock of Bard College for a period after 1979, when it was acquired by Bard College and Simon's Rock College of Bard. In August 2007, it changed to its current name, in an effort "to be more clear about identity" and "to be very clear about the Bard College system."

The school is an "early college", designed for students to enroll immediately after completing the tenth or eleventh grade, rather than after graduating from high school. Simon's Rock is the only accredited four-year early college to date and still the only college or university to take this approach with all of its students. It is one of a number of early college entrance programs that provide opportunities for students to enter college one or more years ahead of their traditional high school graduation date. A majority of students transfer to larger institutions after receiving an Associate of Arts degree after two years, although many stay for four to receive a Bachelor of Arts.

On November 19, 2024, Simon's Rock provost John B. Weinstein announced that Simon's Rock would relocate to Bard's newly purchased Massena Campus, a property in Barrytown, adjacent to the college's main campus in Annandale-on-Hudson, New York, in Fall 2025.
