Asa Buchanan is a fictional character and patriarch of the Buchanan family on the American serial drama One Life to Live. The Texan industrialist father of newly arrived characters Clint and Bo Buchanan, Asa was originated in late 1979 by Philip Carey. Carey portrayed the role continually for nearly three decades, through to his final pre-taped appearance in 2008. Throughout those years, Asa's ruthless business dealings and attempts to both protect and control his family members drive much of the drama in the series.
