Chumash people were the first to inhabit what is now known as Moorpark. A Chumash village, known as Quimisac (Kimishax), was located in today’s Happy Canyon Regional Park. They were hunters and gatherers who often traveled between villages to trade. The village of Quimisac once controlled the local trade of fused shale in the region. The area was later part of the large Rancho Simi land grant given in 1795 to the Pico brothers (Javier, Patricio, and Miguel) by Governor Diego de Borica of Alta California.
Robert W. Poindexter, the secretary of the Simi Land and Water Company, received the land when the association was disbanded. A map showing the townsite was prepared in November 1900. It was a resubdivision of the large lot subdivision known as Fremont, or Fremontville. An application for a post office was submitted on June 1, 1900 and approved by August of that year. The application noted that the town had a railroad depot. The town grew after the 1904 completion of a 7,369-foot (2,246 m) tunnel through the Santa Susana Mountains. Moorpark was then on the main route of the Southern Pacific Railroad's Coast Line between Los Angeles and San Francisco. The depot remained in operation until it was closed in 1958. It was eventually torn down around 1965.
Moorpark was one of the first cities to run off commercial nuclear power in the entire world, and the second in the United States, after Arco, Idaho on July 17, 1955, which is the first city in the world to be lit by atomic power. For one hour on November 12, 1957, this fact was featured on Edwin R. Murrow's "See It Now" television show. The reactor, called the Sodium Reactor Experiment was built by the Atomics International division of North American Aviation at the nearby Santa Susana Field Laboratory. The Sodium Reactor Experiment operated from 1957 to 1964 and produced 7.5 megawatts of electrical power at a Southern California Edison-supplied generating station.
Moorpark College opened on September 11, 1967. Moorpark College is one of the few colleges that features an Exotic Animal Training and Management Program. Moorpark was incorporated as a city on July 1, 1983.
In 1996, Moorpark's Little League All-Star team represented the West Region in the Little League World Series in Williamsport, PA.
In February 2005, a Siberian tiger named Tuffy that escaped from a local residence was shot and killed in one of Moorpark's parks. This created a great deal of uproar, because the animal control officers used a gun instead of a tranquilizer to kill the tiger, primarily because the tiger could not be shot from the proper angle for a tranquilizer to prove effective. Candlelight vigils were held for the late Tuffy. The couple who owned the tiger had moved from a licensed facility in Temecula, California, to an unlicensed facility in the Moorpark area of Ventura County. They lost their U.S. Department of Agriculture exhibitor license because they failed to notify the department of the move within 10 days. The wife pleaded guilty to a federal misdemeanor count of failing to maintain records of exotic felines. The husband pleaded guilty to obstruction of justice, making false statements and failing to maintain proper records. Each was sentenced to home detention, three years probation, and fined $900.
Just a month later, in March 2005, the fairly complete remains (about 75%) of an unusually old mammoth, possibly the rare southern mammoth (Mammuthus meridionalis), were discovered in the foothills of Moorpark at the site of a housing development.[The fossilized skeleton is believed to be from a 800,000 to 1.4 million years old mammoth, which is estimated to have had a weight of ten tons.
In 2006, the Moorpark city council transferred governance of their library from the Ventura County library system to their own newly created city library system. The library, which opened in 1912, celebrated its centennial in 2012.
On February 28, 2006, a housing proposal, North Park Village, which would have added 1,680 houses on 3,586 acres (15 km2) in the north-east area of the city, was defeated by a landslide in a city election.
In 2016, Mike Winters, the Vice President and Historian of the Moorpark Historical Society, published a revised history of Moorpark that covers the years from Moorpark's beginnings to the 1930s. The book, published by Arcadia Publishing is entitled Images of America: Moorpark.
