The Eulogio "Amang" Rodriguez Institute of Science and Technology (commonly referred to as EARIST; Filipino: Kolehiyong Eulogio "Amang" Rodriguez sa Agham at Teknolohiya) is a public college in Santa Mesa, Manila in the Philippines. It was named after Eulogio Rodriguez, one of the longest serving senators in the country.

Founded in 1945 as a vocational-technical high school, it has evolved into a full-fledged higher education institution offering undergraduate and postgraduate degree programs by virtue of the Republic Act 6595.

EARIST has a Level II Status for its 14 degree programs awarded by the Accrediting Agency of Chartered Colleges and Universities in the Philippines (AACCUP). It was also rated Level II based on CHED-DBM-PASUC Leveling Evaluation. With approximately 15,000 students, it has eight colleges, graduate school, and a satellite campus in Cavite.

The institute is envisioned to develop its students in the fields of trades, business, arts, science, and technology education..

The Eulogio "Amang" Rodriguez Institute of Science and Technology (EARIST) was established after the liberation of Manila in 1945. It started as a vocational school with only one room at the second floor of the Mapa High School, nine teachers, a clerk, and 147 students. Its former name was Eulogio Rodriguez Vocational High School (ERVHS).

In July 1946, EARIST acquired its present site in Nagtahan, Santa Mesa, Manila. Apolinario Apilado was appointed as the principal, succeeded by Dr. Hilario Nudas in 1949.

EARIST's development was made possible through three Republic Acts and a Presidential Decree:

• The Republic Act 4072 was jointly sponsored by then Congressman Ramon Bagatsing and Salih Ututalum in 1964, authorized the establishment of the Technical Education Department without changing the name of the school. It was headed by a vocational director.

"Section 1. A vocational technical department which shall offer courses above secondary level is hereby established in the Eulogio Rodriguez Vocational High School in the City of Manila."

• The Republic Act 5088 was sponsored by Congressman Sergio Loyola in 1967, authorized the renaming of ERVHS to Eulogio "Amang" Rodriguez Memorial School of Arts and Trades (EARMSAT) and signaled its separation from the Division of City Schools, Manila. It was headed by a superintendent.
• The Republic Act 6595 was sponsored by Congressman Joaquin R. Roces in 1972, converted EARMSAT to EARIST with a president as its head. This made EARIST into a full-fledged college and authorized the establishment of vocational-technical school branches in each congressional district of Manila.
• The Presidential Decree 1524 which was signed by President Ferdinand E. Marcos on June 11, 1978, that converted Eulogio "Amang" Rodriguez Institute of Science and Technology (EARIST) into a chartered state college with a board of trustees as its governing body and Dr. Hilario G. Nudas, as its first college president.

"Further amending certain sections of Republic Act numbered four thousand seventy-two entitled "an act providing for the establishment of a vocational technical department of the Eulogio Rodriguez Vocational High School in the City of Manila" as amended by Republic Act numbered five thousand eighty-eight entitled "an act converting Eulogio Rodriguez Vocational High School into Eulogio "Amang" Rodriguez Memorial School of Arts and Trades" by providing for a board of trustees, defining the board's powers and duties, and for other purposes."

The Manila Campus of EARIST is along Nagtahan Street in Santa Mesa, Manila. It serves as the main campus.

EARIST Cavite Campus, formerly called EARIST-GASAT (General Alvarez School of Arts and Trades), is a satellite campus. It operates with the funding support from the budgetary allotment of its mother institution, EARIST Manila. It is the only state college in Gen. Mariano Alvarez, Cavite and is accredited by the Commission on Higher Education (CHED) and by the Accrediting Agency of Chartered Colleges and Universities in the Philippines (AACCUP).

Being a government-funded college, it has been providing quality science and technology education with the lowest tuition fee for the less privileged but deserving residents in G.M.A. and other municipalities in Cavite and CALABARZON area. Established on March 24, 1982, EARIST Cavite Campus started by offering vocational and technical courses with Dr. Rodrigo Hipol as the superintendent using the old NASIDA Building. Later, it was transferred to its present campus site, a 31,282-square-meter lot donated by the National Housing Authority (NHA) to the college in 1986.

In 1983, it opened the four-year Secondary Trade Education program and offered the following collegiate courses: Bachelor of Science in Industrial Technology (BSIT) in 1985–1986; Bachelor of Science in Industrial Education (BSIE); and Bachelor of Science in Business Education (BSBE) in 1989–90; Bachelor of Science in Office Administration (BSOA) course in 1999–2000; Bachelor of Science in Computer Science (BSCS) in 1995–96; Bachelor of Science in Hotel and Restaurant Management (BSHRM); and the Bachelor of Science in education (BSE) in school year 2003–2004. Through the collaborative effort of EARIST administration and the municipal and provincial government, led by former Congressman Renato Dragon, its present three-story main building was initially constructed in March 1990 and ten-phase building projects were completed in 1999.

On March 16, 2024, the EARIST administration voided a 'No haircut, no enrollment' provision in its student handbook denying "enrollment to male students, including transgenders, unless they conform to the prescribed hair length and uniform". “This afternoon we facilitated a dialogue between the EARIST administration, led by president Rogelio Mamaraldo, and the affected students led by Red Riotoc of the Bahaghari-EARIST body to dialogue and find ways of solving the problem... Both sides found common ground,” CHED Chair De Vera said. Manila Councilor Joel Villanueva moved for “the strict implementation and enforcement of Ordinance 8695, a measure passed in 2020 meant to protect members of the LGBTQIA+ community".
