Grand Terrace is a city in San Bernardino County, California, United States.

Originally, the area was simply referred to as "the Terrace", but the word "Grand" was added around 1898 due to the beautiful views which surround the city.

In 1905, Seventh-day Adventists, whose medical university is now located in nearby Loma Linda,[8] settled in the area.

Grand Terrace, at the time known as "South Colton", experienced continued growth and development during the Southern California suburbia and sunbelt periods in the late half of the 20th century.

This 22-1/2-mile canal, built at a cost of 2 million dollars, brought water from the Santa Ana River marshlands below The Terrace.

With plenty of irrigation water, Grand Terrace rapidly became an agricultural community featuring fine, quality citrus.

The social activities in the early 1900s centered around the Farm Bureau Extension Service and the Women's Club, followed by the PTA, in the 1930s.

From the very beginning the Chamber was interested in preserving the local identity of the area, and therefore, was a strong supporter of cityhood.

This group did much of the groundwork, which led to the formation of a local governing body in 1976, which was called the Municipal Advisory Council or MAC.

According to the United States Census Bureau, the city has a total area of 3.5 square miles (9.1 km2), all land.

According to the 2010 United States Census, Grand Terrace had a median household income of $64,073, with 6.5% of the population living below the federal poverty line.

Currently the city council consists of Mayor Darcy McNaboe, Sylvia Robles, Douglas Wilson, William Hussey, and Jeff Allen.
