John Ludvik Morkovsky (August 16, 1909 – March 24, 1990) was a Czech American prelate of the Roman Catholic Church. He served as Bishop of Amarillo (1958–1963) and Bishop of Galveston-Houston (1975–1984).
The seventh of ten children, John Morkovsky was born in Praha, Texas, to Alois and Marie (née Raska) Morkovsky. His father came directly to the United States from Moravia, while his mother was the daughter of Moravian immigrants. He was baptized by Rev. Louis P. Netardus at his parents' home. He attended St. John's Seminary in San Antonio from 1924 until 1930, when he was sent to further his studies in Rome at the College of the Propaganda and the Pontifical Gregorian University.
While in Rome, Morkovsky was ordained to the priesthood by Cardinal Francesco Marchetti Selvaggiani on December 5, 1933. He later earned his doctorate in theology in 1936. Upon his return to Texas in 1936, Morkovsky served as a curate at St. Michael's Church in Weimar until 1939. He was a curate at St. Anne's Church in San Antonio from 1939 to 1940, and a professor of canon law, Latin and philosophy at St. John's Seminary from 1940 to 1941. He briefly served as pastor of St. Francis de Paula Church and superintendent of Catholic schools in San Antonio.
