La Porte (from French 'the door') is a city in LaPorte County, Indiana, United States, of which it is the county seat. Its population was estimated to be 21,341 in 2022. It is one of the two principal cities of the Michigan City-La Porte, Indiana metropolitan statistical area, which is included in the Chicago–Naperville–Michigan City, Illinois–Indiana–Wisconsin combined statistical area.

La Porte is located in northwest Indiana, east of Gary, and west of South Bend. It was first settled by European Americans in 1832. The city is twinned with Grangemouth in Scotland.

The settlement of La Porte was established in July 1832. Abraham P. Andrew, one of the purchasers of the site, constructed the first sawmill in that year. The first settler arrived in October, building a permanent cabin just north of what would become the courthouse square.

After the US extinguished land claims by the Potowatomi and other historic tribes of the area by treaty and removal to Indian Territory, in 1833, a federal land office was established in La Porte. People came to this office from newly established surrounding counties to buy land from the government, including Solon Robinson, founder of Crown Point. The office was moved to Winamac in 1839.

By 1835, the settlement had grown to the extent that La Porte was incorporated as a town. A newspaper was established in 1836. La Porte Medical School, the first of its kind in the Midwest, was founded in 1842. An alumnus of school, William Worrall Mayo, established what became the famed Mayo Clinic in Minnesota in 1889.

By 1852, La Porte had become a well-established settlement of considerable size for its time and vicinity, with 5,000 residents. In that same year, it was granted a city charter by the Indiana General Assembly, and the first mayor was elected. La Porte continued to grow, attracting numerous, diverse industries, the largest of which became the Advance-Rumely Company. Advance-Rumely developed and manufactured the Oil-Pull tractor engine, considered to have played a pivotal role in the agricultural development of the Great Plains. By 1869, Advance-Rumely was the largest employer in La Porte.

During the 1850s, numerous maple trees were planted along Indiana and Michigan Avenues in the city by local resident Sebastian Lay. Subsequently, La Porte became known as the "Maple City". Today, Indiana and Michigan Avenues comprise a historic district in the city, containing many homes and other structures of architectural and historical interest. Between 1892 and 1894, the third and current LaPorte county courthouse was erected at a cost of $300,000. The structure is built of red sandstone from Lake Superior, shipped by boat to Michigan City and then by rail to La Porte. The courthouse is considered to be one of La Porte's best-known structures. In 2007 the exterior of the building was extensively restored at a cost of $2.9 million.

La Porte is accessible from Chicago by the South Shore train line, which begins at Millennium Station and ends in Michigan City, Indiana, with several stops in between, including Chesterton and Hudson Lake, Indiana. Both are only a short drive from La Porte.

La Porte has an extensive city park district.

• Allesee Park, (Boyd Boulevard) – is a 6-acre neighborhood park on the south side of the city. It was developed adjacent to a housing subdivision to provide recreational facilities to the neighborhood. The Park was named after George Allesee Sr (18989-1968), long time Physical Director of the La Porte YMCA who also broadcast La Porte Slicers Games on the Radio for 50 years. The park includes a baseball diamond, basketball half-court, benches, parking, playground, and a walking track. Improvements were made in 2000 thanks to a donation by one of his sons to the La Porte Park Foundation.
• Ben Rees Park, (Scott Street) – is a 1.5-acre parcel that is half of a square block located near the Civic Auditorium. The park was the site of the Fourth Ward School in the early 1900s. The school was demolished in the 1920s and the property was donated to the city in the 1940s. The park was named in honor of Ben C. Rees, a local attorney and school board member. A new playground, basketball court and gazebo shelter were installed through the help of community volunteers and contributions.
• Bill Reed Tennis Complex (2150 A Street) – features several tennis courts, parking, water fountains and a pavilion.
• Charles W. Lindewald Park, (Park Street) – is considered La Porte's first park. A parcel of land, 9.4 acres on Lower Lake, was purchased in 1890. The original parcel contained a notable grove of white oaks, of which a few stands of this native timber still remains. Facilities include a picnic shelter with grills, playground, restrooms, water fountains, ball diamond, basketball half-court and 12 lighted horseshoe pits, which are home to the La Porte Horseshoe Pitches Association.
• Clarke Field, (Farrand Avenue) – is a two square block area of 6 acres that was a donation to the city in the late 1930s. The park is generally surrounded with tall, mature fir evergreen trees that provide a buffer for the adjacent residential areas. The main recreational usage at Clarke Field are two ball diamonds, one used primarily by the La Porte High School junior varsity and La Porte Babe Ruth Baseball and the other for younger age levels. The park also contains a playground, ball diamonds, a concession stand, water fountains, and public restrooms.
• Fox Memorial Park, (Truesdale Avenue) – originally started in 1911 with only 15 acres, has grown today to 170 acres. In the early 1900s, flowers, shrubs, and trees were planted to further beautify the hills of mature oak, hawthorn and wild apple. The entire park was landscaped and strolling paths developed. Fox Memorial Park includes Clear Lake, which encompasses approximately 100 acres of the total park. The trees planted in the early 1900s have matured and additional recreational facilities have been developed at the park. The park has ball diamonds, including Ron Reed Field; basketball; playgrounds; picnic shelters with grills; fishing; boating; water fountains; walking and fitness trials; and Thrills ‘n’ Spills Skate Park. The park also contains the Dennis F. Smith Amphitheatre, home to events such as the Arts in the Park program.
• Hastings Park (Monroe St.) – is a small park, featuring a playground and benches.
• Kesling Park (2150 A Street) – is located on the southern edge of the community. It started with a small 2-acre land donation and has since grown through additional donations by the Kesling family to the present day size of 90 acres. Today, residents from all of La Porte enjoy the modern facilities including four ball diamonds, six tennis courts, a walking and nature trail, soccer fields, basketball courts, sledding hill and picnic shelters. The park also contains Fort La Play Porte, a large community-built playground.
• Koomler Park (Miller Street) – covers 4 acres in southern La Porte. It was initially a play area developed by the federal government in the 1940s for children of the workers at the Kingsbury Ordinance Plant. In 1962, this land was transferred to the city for exclusive use as a park. Today, Koomler Park serves the residents of Maple Terrace and offers a ball diamond, basketball court and playground.
• LaPark (1st Street) – is adjacent to Bethany Lutheran Church.
• Rumley Park (Home Street) is a 4-acre neighborhood park that was purchased and developed entirely with federal funds in 1980. It was actually a replacement park for the former Marquette Park, which was located four blocks away. Marquette Park was a piece of donated land that was unsuitable and unbuildable for a park. Rumley Park offers a basketball court, playground, picnic facilities and fishing.
• Scott Field (Jefferson Avenue) – was the result of another land donation of a developer. Originally, in the layout of Scott's Second Addition, 5 acres in the middle of the new housing development was left as a neighborhood play area. The land was donated to the City of La Porte in 1923. It was not until 1952 that the Park Department entered a 99-year lease, for $1 per year, with the school corporation. The park currently includes a shelter, playground, ball diamond, open play, half-court basketball and picnic facilities.
• Soldiers Memorial Park (250 Pine Lake Ave.) – was dedicated in 1928 and contains 556 acres. It is the largest city park and known for its trees, water sports and organized recreational activities.

Also the park provides a variety of active and passive recreational activities including swimming, playgrounds, diamond sports (softball, baseball and t-ball), volleyball, mountain biking, cross-country skiing, fishing and boating.
