Lester Paul Vetter (May 1910 – February 25, 1960) was a Democrat from Coushatta in northwestern Louisiana, who was a member of the Louisiana House of Representatives from Red River Parish from 1952 until his death, with service during the administrations of Governors Robert F. Kennon and Earl Kemp Long.
Vetter is listed in both the 1920 and the 1930 census at the ages of nine and nineteen, respectively, as living in St. Mary Parish in South Louisiana. He attended Louisiana State University in Baton Rouge.
Immediately prior to his legislative tenure, Vetter was from 1948 to 1952 the mayor of Coushatta. Vetter was also a secretary-treasurer and then the president of the Red River Parish Fair Association, in which capacity he obtained a grant for a needed new exhibition barn.
Vetter died in a New Orleans hospital shortly before the end of his legislative term. He was survived by his widow, the former Anna May Posey (1912-2004), a teacher and businesswoman and one of three children of George J. Posey. The Vetters had two children, a son and a daughter. He is interred at Springville Cemetery in Coushatta.
