The flag of Pembrokeshire (Welsh: Baner Sir Benfro) is the flag of the Welsh county of Pembrokeshire.
The flag was designed by Councillors Peter Stock, Dewi Pritchard, Jim Brock and Marjorie Jacobs in the 1970s after the abolition of Pembrokeshire County Council. A statement by Peter Stock, 'The flag was dedicated as the official flag of Pembrokeshire, at Pembroke Castle at a ceremony on 28 July 1988 with a march past by the band of The Queen's Dragoons Guards.' The ceremony was recorded for posterity.[1]
Joffre Swales, founder and conductor of the Haverfordwest Town Band, wrote a march entitled "The Pembrokeshire Flag" for the band to perform on marches around the county.
