Madeleine Duncan Brown (July 5, 1925 – June 22, 2002) was an American woman who claimed to be a longtime mistress of United States President Lyndon B. Johnson. In addition to claiming that a son was born out of that relationship, Brown also implicated Johnson in a conspiracy to assassinate President John F. Kennedy.

Brown described her background in her 1997 autobiography, Texas in the Morning: The Love Story of Madeleine Brown and President Lyndon Baines Johnson. According to Brown, she was raised in a middle-class Catholic household in Dallas, Texas, where her father was a utility company supervisor and her mother was a housewife. She stated that she attended W. H. Adamson High School. Brown said at the age of 19 she married James Glynn Brown, a childhood sweetheart and neighborhood soda jerk, whom she divorced in 1955. She described her husband as a veteran of the United States Marine Corps whose "war experiences had shattered his nerves, and turned him into a hopeless, physically abusive drunkard". Brown said that he "was eventually institutionalized in a veteran's hospital for 'chronic paranoid schizophrenia'". According to Brown, she left her husband in 1948 while he was in the hospital, returning to Dallas with her two-month-old son, Jimmy Glynn Brown. She said that she was subsequently hired that same year by Glenn Advertising and was promoted to media buyer whose responsibilities including purchasing radio advertising time.

On November 5, 1982, Brown spoke at a news conference held at the Dallas Press Club, alleging that she had an extramarital relationship with Johnson for almost twenty years. She said that the affair began in 1948 after a party at the Adolphus Hotel in Dallas and lasted until 1967.The Dallas Morning News also published the allegations under the headline "Dallas Woman Claims She Was LBJ’s Lover", noting that spokespeople for Lady Bird Johnson and the Johnson family rejected the claims. Brown's statement, in which she said she wanted to "clear the record", came three weeks after published reports of an affair between Johnson and Alice Glass.
