The Elphinstone baronetcy, of Sowerby in the County of Cumberland, was created in the Baronetage of the United Kingdom on 25 May 1816 for Major-General Howard Elphinstone, a veteran of the Peninsular War. He was the youngest son of John Elphinstone, a captain in the Royal Navy and admiral in the Russian Navy.
The heir presumptive to the baronetcy is a cousin of the 6th baronet, Henry Charles Elphinstone (born 1958).
