Magnolia Park (Spanish: Parque Magnolia) is an area of the East End, Houston, Texas, located near the Houston Ship Channel. One of the oldest Hispanic neighborhoods in the City of Houston, Magnolia Park was formerly incorporated as the City of Magnolia Park in eastern Harris County.

In 1890 Magnolia Park was laid out on a 1,374-acre (556 ha) site on Harrisburg Road across Brays Bayou from Harrisburg and 7 miles (11 km) downstream from Houston. The plot was owned by Thomas M. Brady, and the community was named for the 3,750 magnolias planted by developers. The Magnolia Park community was organized in 1909. The city incorporated in 1913, even having its own police force.

Magnolia Park originally had non-Hispanic White Americans. Mexican-Americans from South Texas started to settle in Magnolia Park in 1911. By the 1920s, many Mexicans fleeing the Mexican Revolution settled in Magnolia Park. The construction of the Houston Ship Channel and area industries attracted Mexicans. They worked in different fields depending on their gender, with women working in factories, stores, and textile plants and men in working in industries such as construction and maintenance of the Ship Channel, cotton compresses and cement plants.

Canal Street in Magnolia Park was originally known as "German Street." Circa 1918 it was renamed "Belgium Street" in honor of a country invaded by Germany in World War I. At a later point the name was harmonized with that of the section in the pre-merger City of Houston, known as Canal Street.

Magnolia Park was annexed to Houston in October 1926. The Mexican community stayed centered in Magnolia Park partly due to discrimination from elements of the Anglo community. By 1926 Magnolia Park was called "Little Mexico" by Anglo residents of Houston. Its business district had businesses such as restaurants, grocery stores, barber shops, bakeries, drugstores, and gasoline stations. By 1929 it was the largest Mexican settlement in Houston.

A League of United Latin American Citizens (LULAC) branch was organized in 1934. In 1935 a Ladies LULAC council was organized. By the 1930s political organizations such as the Club Femenino-Chapultepec had been established to protest segregation, promote Mexican-American culture, and provide recreation. By the World War II period Magnolia Park was considered to be within the East End. Due to the war, Mexican-Americans in the Southwestern United States were drawn to Houston for jobs, and so the local population increased. By the time of World War II youth gangs were active in Magnolia Park.

By the 1960s most Mexican-Americans in Magnolia Park were poor, and the middle class in Magnolia Park had expanded due to programs established by President of the United States Lyndon Baines Johnson. The Magnolia Park YWCA's women hosted the Conferencia de Mujeres por la Raza in 1971. The percentage of the residents below the poverty line in 1978 was up to 20%. When the 1980s oil bust occurred, fifty factories in and around Magnolia Park closed due to the drop in oil prices, causing thousands of Mexicans to lose their jobs. Magnolia Park had 14,000 residents in 1990. The Magnolia Park community celebrated the neighborhood's 100 year anniversary on Saturday October 17, 2009.

Many of the Historical Buildings are still there and can be seen throughout all of Harrisburg and Canal St.
