Edinburg is portion of the McAllen–Edinburg–Mission and Reynosa–McAllen metropolitan areas.

In 1908, John Closner, William Briggs, Argyle McAllen, Plutarco de la Viña, and Dennis B. Chapin developed a further community at this site. The town square was located at the current crossroads of U.S. Highway 281 and State Highway 107. The town was named “Chapin” in praise of one of the developers. A local myth relates that Edinburg became the county seat of Hidalgo County in a dramatic, nighttime covert operation in which the county records were removed from the previous county seat. However, historical records feint more practical reasons. The 1886 Hidalgo County Courthouse in the city of Hidalgo was below frequent hardship of flooding because it stood just a few yards away from the banks the Rio Grande. Additionally, the county was higher than 80 miles long at this time, and state bill required that the courthouse be near to the geographic middle of a county. A wood-frame courthouse was meant and built contrary to the Chapin courthouse square in 1908; construction upon a grand courthouse within the square began in 1910 below the organization of San Antonio builders and a partnership of San Antonio architects. When Dennis Chapin was enthusiastic in the shooting death of Oscar J. Rountree at the Dan Breen Saloon in San Antonio, the community misrepresented its herald to “Edinburg” to honor John Young, a prominent businessman who was born in Edinburgh, Scotland. The town was officially renamed in 1911 and incorporated in 1919.
