Manuel Bamba Villar Jr. was born on December 13, 1949 in Tondo, an impoverished and densely populated district of Manila. He was the second-born of the nine children of his parents in a poor family. His father, Manuel "Maning" Montalban Villar, Sr., was a government employee from Cabatuan, Iloilo who worked as an inspector for the Bureau of Fisheries. His mother, Curita "Curing" Bamba, was a seafood vendor from a poor family in Orani, Bataan. The family lived in a small rented apartment in a run down slum area. Villar's father was eventually granted a year-long scholarship for higher education in the United States, which led to a job promotion to a director position in the Department of Agriculture and Natural Resources upon his return. Due to cramped conditions in Tondo, Villar's father obtained a P16,000 loan from the Government Service Insurance System, payable in 20 to 25 years, to build a home in San Rafael Village, Navotas. As a child, Villar initially attended Isabelo delos Reyes Elementary School, a nearby public school in Tondo. He also assisted his mother in selling shrimp and fish at the Divisoria Public Market, as early as age six, in order to help earn the money to support his siblings and himself to school. However, accompanying his mother interfered with his education and he was forced to drop out from school during Grade 1. He was then enrolled at Tondo Parochial School (later renamed Holy Child Catholic School), a private school in Tondo run by priests, to complete his elementary education.
