John Soursby Glover, Jr. (born August 7, 1944) is a Tony Award-winning and Emmy Award-nominated American actor. He is perhaps best known for a range of villainous roles in films and television, including Lionel Luthor in the TV series Smallville.

John Glover (18 February 1767 - 9 December 1849) was an English/Australian artist in what is known as the early colonial period of Australian art. In Australia he has been dubbed the father of Australian landscape painting.

John Glover (November 5, 1732 - January 30, 1797) was an American fisherman, merchant, and military leader from Marblehead, Massachusetts, who served as a brigadier general in the Continental Army during the American Revolutionary War.

Glover was born in Salem, Massachusetts. After his father's death, his mother moved to Marblehead. Glover became a shoemaker and a fisherman. He married Hannah Gale in 1754, with whom he had eleven children.

Glover was active in the militia for many years before the Revolution. In 1775 he was elected lieutenant colonel of the Marblehead militia regiment, and became commander of the unit after the death of Colonel Jeremiah Lee in April 1775. Glover marched his regiment to join the siege of Boston in June 1775. At Boston, General George Washington chartered Glover's schooner Hannah to raid British supply vessels, the first of many privateers authorized by Washington. For this reason the Hannah has been called the first vessel of the United States Navy.

The Marblehead militia or "Glover's Regiment" became the 14th Continental Regiment. This regiment became known as the "amphibious regiment" for their vital nautical skills. After Washington lost the Battle of Long Island in August 1776, Glover's Marbleheaders evacuated the army to Manhattan in a surprise nighttime operation, saving them from being entrapped. In subsequent actions of the New York campaign the regiment fought well against the British at Kip's Bay and Pell's Point. The last action of the regiment was its most famous: ferrying Washington's army across the Delaware River for a surprise attack at Trenton in December 1776. The regiment was disbanded as enlistments expired at year's end.

Glover went home to tend to his sick wife and look to business affairs. He turned down a promotion to brigadier general in February 1777, but rejoined the war after a personal appeal from General Washington. He served in the successful Saratoga campaign in 1777 and the failed Battle of Rhode Island in 1778. He was stationed along the Hudson River for the remainder of the war, guarding against British moves up the river from New York City.

Hannah, Glover's first wife, died in 1778. He married again in 1781 to Frances Fosdick. He retired from the army in 1782 in poor health. Failing to secure a job with the national government, he served in various local offices in his remaining years. He died at age 64 in Marblehead after contracting hepatitis.

Various things have been named in his honor. On November 20, 1783, he was awarded the charter for the town of Glover, Vermont, as its prime proprietor, in honor of his service. The frigate USS Glover is named for him. Glover's Rock in the Bronx is a memorial to him and Glover School in Marblehead was named after him in 1916.

John William Glover (born 28 October 1876 in West Bromwich, Staffordshire, died 20 April 1955 in Dudley, Staffordshire), sometimes known as Jack Glover, was an English professional footballer who played as a right-back. He made 174 appearances in the First Division for Liverpool and Birmingham, and in 1900–01 won the league championship with Liverpool. He was a strong-tackling defender and formed an excellent full-back pairing with Frank Stokes at Birmingham.

After retiring from football he kept a public house in Dudley and also represented Shropshire at bowls.
