There have been seven baronetcies created for persons with the surname Parker, three in the Baronetage of England, two in the Baronetage of Great Britain and two in the Baronetage of the United Kingdom. Two of the creations are extant as of 2008. Though none of the different families of baronets were related, several supplied a number of flag officers to the Royal Navy.
