The Valenzuela City School of Mathematics and Science (Filipino: Paaralang Pang-matematika at Pang-agham ng Lungsod ng Valenzuela), also referred to as VCSMS and ValMaSci, is a specialized public high school in Valenzuela City, Philippines.

Established in 2003 as the Valenzuela City Science High School (Mataas na Paaralang Pang-agham ng Lungsod ng Valenzuela), it offers a special advanced curriculum with emphasis in the fields of mathematics and science to residents of Valenzuela City. The school also has a specialized range of subjects in technology, engineering, and language.

The Science Oriented Experimental Class (SOEC) was initiated in school year 1996–1997 "to shape and produce globally competitive and morally upright individuals who will serve as the foundation of [the] nation's great success." It was an education program organized by former Valenzuela City Mayor Jose Emmanuel Carlos. The class was housed at the Valenzuela National High School (VNHS), in Barangay Marulas, and it was composed of 40 academically outstanding students.

On May 14, 2003, seven years after SOEC was created, Valenzuela City Ordinance No. 37 s. 2003 was approved, establishing a science high school from the original SOEC. The school, under the name Valenzuela City Science High School, was to be funded by the local School Board of Valenzuela.

On February 8, 2003, a memorandum was sent to all principals of public and private elementary schools in the city, requesting to inform graduating students to apply for the qualifying examination for the upcoming admission of first-year high school students at VCSHS. With 200 applicants administered, 108 students passed the admission tests (consisting of an intelligence quotient test, a proficiency test, and an interview). They enrolled at the new school with Brian E. Ilan as the first principal. On June 9, 2003, the first VCSHS Parents, Teachers, and Community Association (PTCA) was formed.

From the original six teachers, the institution added eight. Additional students made the VCSHS community larger as the years passed. At the beginning of the school year 2005–2006, VCSHS moved to its newly constructed building at A. Marcelo Street in Barangay Dalandanan. City Mayor Sherwin Gatchalian inaugurated the new house, and 4th year students entered VCSHS. According to the teachers at the time, a recorded shortest graduation happened for the 15 students of SOEC passing the 4th year curriculum of ValSci.

In early 2014, Valenzuela City Mayor Rexlon Gatchalian announced the construction of a new state-of-the-art campus under the name Valenzuela City School of Mathematics and Science. This is a part of the Education 360° Investment Program of the local government that included feeder programs, the provision of school supplies, and training for students, parents, and teachers. Rexlon Gatchalian explained, "This is a large-scale investment to shore up the local education system." Out of the ₱300 million budget allotted to the plan, ₱199 million was spent on the construction and outfit of the new school campus. He said that the soon-to-rise school is the "best education investment [the] city has ever made."

The groundbreaking of the new school site in Barangay Malinta was held on January 27, 2014. Rexlon Gatchalian, local government officials, the Valenzuela City Science High School faculty and students, and the Department of Education (DepEd) secretary Armin Luistro attended the ceremony. The mayor praised the school's NAT scores, which are the highest in Metro Manila, and the high passing rate for UPCAT. He said in another interview that "these classrooms will be available for use when classes open in June this year."

The changing of the school name to Valenzuela City School of Mathematics and Science gained much dispute around the school community. Rexlon Gatchalian responded by saying, "The reason is because we do better in math compared to science." DepEd secretary Luistro said, "I'm okay with the name change, but I'm more concerned with the substantial changes in the curriculum, the quantity of its graduates, and how many of them will take math or science-related courses in college." The new name was proposed by city councilor Lorena Natividad-Borja. It was signed by the mayor as City Ordinance No. 120, which includes the enhancement of the mathematics program in the new curriculum.

The campus was completed in August 2014, six months after the groundbreaking ceremony, and was inaugurated on September 1, 2014. Luistro praised the city's education program by stating, "I am very much impressed by this city's investment in education. Aside from this new city school, Valenzuela City has found solutions for the decongestion of schools within their area through the 'busing system,' by transferring students from one school to another." Rexlon Gatchalian, during the tour of the newly constructed building, said, "With something as grand as this, we want to stir an interest in mathematics and science among the youth in Valenzuela City."

The four-story school building is a full Wi-Fi zone and contains 20 classrooms, which can hold 35 to 40 students each, and physics and robotics, speech, computer, chemistry, biology, and mathematics laboratories. Each of the six laboratories is equipped with an interactive Smart Board, while the science (physics and robotics, chemistry, and biology) laboratories have two areas: one for lecture and another for experiments.

Dubbed as the "crown jewel" of the city when it comes to education investments, the Valenzuela City School of Mathematics and Science is said to be envisioned as part of the most high-tech and advanced mathematics and science schools in the Philippines. To keep the building, its facilities, and other tangible concerns proper, the city government assigned personnel to function as building administrators. Classes at the new campus began on September 8, 2014. Luistro said, "My prayer is that Valenzuela City School of Mathematics and Science may produce the best and brightest scientists of the country."
