Leopold Copeland Parker Cowper (March 1811 – July 17, 1875) was a lawyer who served as (seventh) lieutenant governor of the Restored government of Virginia from November 1863 until June 1865 and then as the eighth Lieutenant Governor of the Commonwealth of Virginia from June 1865 until September 1869 under Governors John Letcher, William Smith, Francis Harrison Pierpont and Henry H. Wells.
[1] Cowper was born on the Macclesfield Estate,[1] the family's plantation since a land grant by King Charles the I in 1638,[2] on the Isle of Wight County, Virginia.
In January 1817 his mother, Ann Pierce Parker Cowper, daughter of former congressman Josiah Parker, was granted a legal separation by the Virginia General Assembly, and she received legal custody of her children.
Although the candidates for governor and attorney general were unopposed, Cowper was challenged by Gilbert S. Miner, whom he defeated in the election held on May 28, 1863.
Cowper died in 1875 and was buried at Macclesfield, his family's estate at Smithfield in Isle of Wight County.
