Conroe is a city in Texas, United States. It is the seat of Montgomery County and a principal city in the Houston–The Woodlands–Sugar Land metropolitan area. It is about 40 miles (64 km) north of Houston.
As of 2019, the population was 91,079, up from 56,207 in 2010. According to the Census Bureau, Conroe was the fastest-growing large city in the United States between July 1, 2015, and July 1, 2016.
The city is named after Northern-born Union Cavalry officer and Houston lumberman Isaac Conroe. Conroe founded a sawmill there in 1881. The city originally gained in wealth due to the lumber and oil industries. Originally named "Conroe's Switch", the area saw an influx of residents in the late 19th century due to the lumber demands on the piney wood forest of the area.
George W. Strake discovered the Conroe Oil Field in 1931. Distillate and natural gas were produced from the Cockfield Formation at a depth of about 5,000 feet (1,500 m). A second well in 1932 produced 1200 BOPD. By 1935, the field had produced 40 million barrels of oil.
During the 1930s, because of oil profits, the city boasted more millionaires per capita than any other U.S. city, though only briefly.
