Todd Manning is a fictional character from the ABC daytime drama One Life to Live. The role was originated in 1992 by actor Roger Howarth, and is currently being portrayed by actor Trevor St. John.

The character was conceived as a short-term role; Howarth is credited with "turning what was a day player role into a compelling, long-term character." Initially designed to be a ruthless, cunning and one-dimensional villain, throughout the years Todd has evolved into a complex character, often selfish and acting the villain but also passionate about protecting his loved ones and even showing kindness and a conscience.

During his time in the fictional town of Llanview, Pennsylvania, the character has had much trouble with the law, including the infamous gang rape of Marty Saybrooke. In 1994, it was revealed that he was the son of Victor Lord, and half-brother to longtime One Life to Live heroine Victoria Lord.

Todd remarried longtime love Blair Cramer for the fifth time in September 2007. Todd and Blair have two living children, Starr and |Jack. Todd's third child, a son by the mentally unstable Margaret Cochran, was kidnapped at birth and later presumed dead; in 2007 Todd discovered that the boy was in fact alive and being raised as "Tommy McBain" by people he knew. Todd was awarded custody, but Tommy's adoptive mother Marcie McBain fled with the child. With Marcie and his son still at large, on December 20 2007 Todd announced that "Tommy" would be renamed "Sam Manning," in honor of his deceased mentor and friend, Sam Rappaport.

Todd has been the subject of numerous soap opera articles, been alluded to and studied in books, and inspired the creation of a doll in his likeness. He has been called daytime's most popular character, and is considered one of the show's breakout characters.
