Remy Amador Presas (December 19, 1936 – August 28, 2001) was the founder of Modern Arnis, a popular Filipino martial art. Born in the Philippines, he moved to the United States in 1974, where he taught martial arts via seminars and camps. In 1982, he was inducted into the Black Belt Hall of Fame as instructor of the Year. He published several books and videos on Modern Arnis and is recognised as the "Father of Modern Arnis".

Presas was born in the town of Hinigaran, Negros Occidental, Philippines, the son of Jose B. Presas, a businessman, and Lucia Amador.

At the age of six he began studying arnis with his father, then with his grandfather, Leon Presas, as well as his uncle. By the age of fourteen he had had his first stick fighting match with a Sinawali master, who Presas knocked out with one stick hit. He travelled across the Philippine Islands to learn from other masters and to compete in stick-fighting competitions and many street fights. Presas eventually focused on Balintawak Eskrima, but earned a 6th degree black belt in Shotokan Karate and a black belt in judo. His brothers (Roberto and Enrnesto) also trained in Arnis from a young age. Ernesto A Presas, his younger brother, studied in Japan and learned several martial arts. The brothers learned from their father and grandfather and other relatives a style called "family style", which can still be seen in some elements of "Modern Arnis" and in "Arnis Presas style." Despite similar methods and development, the brothers went slightly different routes. Remy moved to the US while Ernesto stayed in the Philippines, but travelled extensively while teaching Arnis.

In 1966 Remy Presas began developing his own system which he called "Modern Arnis" by identifying the basic concepts of the numerous systems he had learned and merging them. By 1969 Modern Arnis had been approved by the Philippine Amateur Athletic Federation as a regular subject to be taught at the National College of Physical education.

Remy was the Arnis consultant for the 1974 Philippines produced film The Pacific Connection. While working on this film he instructed (and became friends with) US actor Dean Stockwell.

Beginning with a small gymnasium in Bacolod in the 1950s, Remy attempted to spread the art to the local youth as both a cultural legacy and a form of physical development or sport. Remy instituted a ranking system with Modern Arnis to identify the ability level of each student: likas(green belt), likha(brown belt), and lakan(black belt). Lakan encompassed ten degrees. He issued certificates of rank, and began using the title Guro which became widespread throughout all Filipino martial arts circles. Presas developed what came to be known as the "Arnis Uniform" - consisting of loose fitting cotton trousers and a karategi style top low cut at the waist.

In 1982, Presas was inducted into the Black Belt Hall of Fame as instructor of the Year. In 1994, he was again honored by Black Belt as Weapons Instructor of the Year.

Presas formed the International Modern Arnis Federation (IMAF) in 1970 as the principal organization for the promotion and administration of Modern Arnis in North America. The organization was responsible for maintaining records of promotions and other administrative tasks. After the founders' death in 2001, these duties have since been passed on to MARPPIO (Modern Arnis Remy P. Presas International Organization), which is operated by the Remy's eldest son Remy P. Presas Jr with the aid of his other children and the rest of the Presas Family.
