The Bayntun-Sandys Baronetcy, of Misserden Castle in the County of Gloucester and of Chadlington Hall in the County of Oxford, was a title in the Baronetage of the United Kingdom. It was created on 26 September 1809 for Edwin Bayntun-Sandys. Born Edwin Sandys, he had assumed the additional surname of Bayntun by Royal sign manual in 1807. His eldest son Edwin Windsor Bayntun-Sandys was knighted in 1825 but predeceased his father, as did his only brother Miles Allen Bayntun-Sandys (d. 1813). Consequently, the title became extinct on Bayntun-Sandys's death in 1848.
