Logansport is a town in western DeSoto Parish adjacent to the Sabine River in western Louisiana, United States. The population was 1,340 in 2020. It is part of the Shreveport–Bossier City metropolitan statistical area.

The area, long a disputed boundary even after the Louisiana Purchase, was part of a neutral territory negotiated by Gen. James Wilkinson and Lt. Col. Simón de Herrera on November 6, 1806.

The Adams–Onís Treaty of 1819, that was not ratified until 1821, would have been a solution but in 1821 Mexico's independence reignited the dispute. Dr. Logan moved to the area in 1830 began practicing medicine in Louisiana and Texas. He chartered a ferry business in the area and it became known as Logan's Ferry.

Texas won independence in 1836, and the newly formed Republic of Texas agreed to the Adams–Onís Treaty, so the Sabine River became the international boundary. The survey crew began the demarcation process on May 20, 1840, at the Gulf of Mexico, and work was completed in 1841. Boundary markers were placed along the boundary, that included one in Logansport. This marker apparently is the only one surviving, meaning it is the only known international boundary marker in the United States. The Texas Annexation of 1845, ended nine years of the Sabine River international boundary.

The name Logansport was given to the town when a post office was established February 28, 1848. There were few people living in the town prior to the arrival of the railroad. With the arrival of the railroad, there was an influx of gamblers and others of questionable character, along with the citizens of better repute. At one time Logansport had more saloons than grocery stores. The town began to grow and it was incorporated. The first election was held on June 25, 1887. In this election there were only 15 qualified voters listed. Elijah Price was elected mayor, along with five other trustees. Oil and gas were also a very important source of income for the early citizens of Logansport.
