Taylorsville High School is a public high school established in 1981, located in Taylorsville, Utah, United States. The principal is Dr. Garett Muse. The mascot is the Wilbur the Warrior. The enrollment is around 2,900 students and represents many different ethnic groups. Taylorsville High is one of eight high schools in Granite School District.

Taylorsville High is located in the central part of the Salt Lake Valley and was built in 1981 to serve the growing population of the Taylorsville area. School boundaries are roughly Jordan River to 3100 West and 4100 South to 6600 South (excluding the area between 4500 S and 4700 S and approximately Jordan River and 950 W).

Taylorsville has successful programs for AVID (Advancement Via Individual Determination), JROTC and Latinos in Action, along with a large AP program.

Taylorsville High offers nineteen different Advanced Placement courses along with several Honors courses in core subjects. Advanced Placement courses are created by the College Board and offer college-level material and exams to high school students. Students may receive course credit at colleges and universities across the country if they earn a high score on the exam.

Taylorsville also offers Concurrent Enrollment (CE) classes; these are college-level classes that are offered to juniors and seniors, in which students can earn both high school and college credit at the same time. Concurrent Enrollment classes are taught by Taylorsville faculty who have been approved by Salt Lake Community College or Utah Valley University as adjunct faculty members. Concurrent enrollment credit can be transferred to most state colleges.

Taylorsville has a large AVID program, and was recognized as an AVID Highly Certified Site for 2017–18. AVID is an in-school academic support program that helps prepare students for college, by teaching them skills needed to succeed in college. AVID places academically average students in Honors, CE, and AP classes, and then provides support to help the student see success in these more advanced classes. The AVID program continues to have a 100% college acceptance rate, meaning every AVID senior has been accepted into a college or university.

In January 1994, Taylorsville High was approved to offer a JROTC program to students. Taylorsville's JROTC program has earned the Unit of Distinction Award seven out of eight years possible. The program teaches students the Army values (Loyalty, Duty, Respect, Selfless Service, Honor, Integrity, and Personal Courage), helps students get back on track or stay on track for graduation, and excellent leadership skills to use throughout their life. The original JROTC instructors were Lieutenant Colonel (R) Horton and First Sergeant (R) Heikel, the program is currently under the direction of Lieutenant Colonel (R) Warner and Sergeant First Class (R) Wilson. The JROTC program is open to all students of Granite School District.

The mission of JROTC is to motivate young people to be better citizens.  A student enrolled in JROTC acquires the title of “cadet” – an officer-in-training.  Designed to prepare cadets for the ever-changing role of being a leader in modern society, the program uses military structure to teach cadets discipline, respect, and how a hierarchy of management levels interacts to accomplish any complex task.  As cadets proceed through the Program they acquire basic life skills, become more physically fit, and develop a sophisticated understanding of government, history, and management.  The Program is more than classrooms and textbooks; it is a hybrid, hands-on enterprise to create a better citizen under the close coaching, counseling, and mentoring of accomplished Army-veteran instructors.  All cadets are encouraged to participate in the extracurricular teams wherein unit cohesion, mutual support, camaraderie, and leadership grow.
