Alhambra Senior High School (AHS) is a public high school in Martinez, California, United States which was first established in 1897. It is a part of the Martinez Unified School District. During the 2006-2007 academic year, the school had enrollment of approximately 1400 students. The school's mascot is "Spike" the bulldog, who can often be seen in appearances with "Spikette" at football games and rallies.

From 1895 to 1899, a private school, known as the Martinez Academy, then a private school provided high school classes.

The discontinuance of the academy left Martinez without a high school. (Contra Costa Gazette January 20, 1956) In July 1901, the Alhambra Union High School District was organized. It was the second of the present day high schools to be instituted and one of four organized in the same year. Alhambra Union High School was established in 1901 according to the minutes of the school board meeting on July 31, 1901. The school mascot was the Panther from 1927 until 1947 when they changed their mascot to the Bulldogs.

Alhambra's campus was built into one of the Bay Area's characteristic rolling hills. The campus was renovated in 1994, and is now set in a Spanish style reminiscent of the old campus. In 2003, the Center for the Arts (Performing Arts Building or PAB) was completed, which seats 350 and plays host to theatrical and musical performances. This is a marked improvement for the school's drama department, which previously performed in the school's "multi-use room", a combination cafeteria and stage space. Most recently, the drama department received a new Black Box theater. The Center for the Arts also features rooms outside that are used to exhibit art. The Center for the Arts also has a large projector screen that can either hang down or retract into the ceiling above. This screen is often used for awareness programs for the students.

The school's synthetic field for football, baseball, soccer, and lacrosse borders the main avenue through town, and an all weather track, tennis courts and basketball are set on the top of a hill. The renovation also produced a large gym facility and a student commons.

All throughout the campus are student-made paintings on doors, walls, and seating areas. Often, the paintings are remakes of other famous paintings, but there are original works as well. For example, in between the F and H Buildings are low concrete walls with numerous flags from different countries painted on top. Some wall paintings depict famous people or musical instruments.
