Carl Bert Albert (May 10, 1908 – February 4, 2000) was an American lawyer and politician who served as the 46th speaker of the United States House of Representatives from 1971 to 1977 and represented Oklahoma's 3rd congressional district as a Democrat from 1947 to 1977.

At 5 feet 4 inches (1.63 metres) tall, Albert was affectionately known as the "Little Giant from Little Dixie". Albert held the highest political office of any Oklahoman in American history.

Albert was born in McAlester, Oklahoma, the son of Leona Ann (Scott) and Ernest Homer Albert, a coal miner and farmer. Shortly after his birth his family moved to Bugtussle, a small town just north of McAlester. He grew up in a log cabin on his father's farm. In high school he excelled in debate, was student body president, and won the national high school oratorical contest, earning a trip to Europe. During this time he was an active member of his local Order of DeMolay chapter; he is an inductee of the Order of DeMolay Hall of Fame. Albert later petitioned his local Masonic Lodge and became an active Freemason. He entered the University of Oklahoma in 1927. There, he majored in political science and won the National Oratorical Championship in 1928, receiving an all-expense-paid trip to Europe. He earned enough money to fund the rest of his undergraduate education through working in the college registrar's office and participating in the Reserve Officers' Training Corps. While at Oklahoma, he was an accomplished amateur wrestler, a member of the Kappa Alpha Order fraternity, and a member of the RUF/NEKS. He graduated Phi Beta Kappa in 1931, was the top male student, then studied at the University of Oxford on a Rhodes Scholarship. He received a Bachelor of Arts in jurisprudence and Bachelor of Civil Laws from St Peter's College before returning to the United States in 1934. He opened a law practice in Oklahoma City in 1935. He worked for a series of oil companies in leasing work until the start of World War II.

Albert joined the United States Army as a private in 1941. He served briefly with the 3rd Armored Division, but was soon commissioned a second lieutenant in the Army Air Forces. While in the army, Albert married Mary Harmon on August 20, 1942, in Columbia, South Carolina, just before he was sent to the South Pacific. The couple had two children, Mary Frances and David. Albert served in the Judge Advocate General Corps as a prosecutor assigned to the Far East Air Service Command. He earned a Bronze Star Medal and other decorations and left the Army with the rank of lieutenant colonel in 1946. He remained in the Army Reserve after the war, and retired in 1968 with the rank of colonel.

Albert was elected to Congress for the first time in 1946. He was a Cold War liberal, and supported President Harry S. Truman's containment of Soviet expansionism and domestic measures like public housing, federal aid to education, and farm price supports. Speaker of the House Sam Rayburn noticed his diligence as a legislator and began inviting him to informal meetings in the speaker's office. Rayburn also advised Albert to seek the chairmanship of the Agriculture Committee in 1949. Albert was appointed House Majority Whip in 1955 and elected House Majority Leader after Rayburn's death in 1961.

Albert seemed to describe himself as a political moderate. He said, he "very much disliked doctrinaire liberals –– they want to own your minds. And I don't like reactionary conservatives. I like to face issues in terms of conditions and not in terms of someone's inborn political philosophy."

Albert was inducted into the Oklahoma Hall of Fame in 1957.

As Majority Leader, Albert was a key figure in advancing the Democratic legislative agenda in the House, particularly health care legislation. Medicare, the federal hospital insurance program for persons 65 and older, was initially proposed by the Kennedy Administration as an amendment to the Social Security program. Albert knew the bill had insufficient Congressional support for passage due to the opposition of ten Republicans and eight southern Democrats. He advised President Kennedy to seek Senate passage of the measure first. Albert calculated that the Senate should bring it to the House as a conference committee report on their own welfare bill, instead of trying direct introduction into the House.
