William Matthews Merrick (September 1, 1818 – February 4, 1889) was a United States circuit judge of the United States Circuit Court of the District of Columbia, a United States representative from Maryland and an associate justice of the Supreme Court of the District of Columbia.

Education and career
Born on September 1, 1818, near Faulkner, Charles County, Maryland, Merrick was the son of William Dunhurst Merrick and his wife. He graduated from Georgetown College in 1831, studied law at the University of Virginia, and read law in 1839 to prepare for the bar.

Merrick admitted to the bar and entered private practice in Baltimore, Maryland from 1839 to 1844. He continued private practice in Frederick, Maryland from 1844 to 1854. He served as deputy attorney general for Frederick County, Maryland from 1845 to 1859. He resumed private practice in Washington, D.C. from 1854 to 1855.

Circuit Court service
Merrick was nominated by President Franklin Pierce on December 14, 1855, to a seat on the United States Circuit Court of the District of Columbia vacated by Judge James Dunlop. He was confirmed by the United States Senate on December 14, 1855, and received his commission the same day. His service terminated on March 3, 1863, due to abolition of the court.

Civil War and removal from office
While a circuit judge, Merrick is best known for his role in the case of United States ex rel. Murphy v. Porter during the American Civil War. He was placed under house arrest by General Andrew Porter in relation to a writ for habeas corpus concerning a soldier stationed in Washington, D.C. During the affair, President Abraham Lincoln ordered Secretary of State William H. Seward to suspend Merrick's salary. Merrick was released from house arrest in December.

His name came up in discussions by the United States Senate over whether to abolish the D.C. Circuit Court, with opponents of the bill claiming that it was a stratagem to turn Merrick and his fellow judges out of office. Senator Henry Wilson claimed that Merrick's heart "sweltered with treason" and that his house had become a hotbed of pro-secessionist sympathizers.
