Lee County is a county located in east central Alabama. As of the 2020 census the population was 174,241. The county seat is Opelika, and the largest city is Auburn. The county was established in 1866 and is named for General Robert E. Lee (1807–1870), who served as General in Chief of the Armies of the Confederate States in 1865. Lee County comprises the Auburn-Opelika, AL Metropolitan Statistical Area, which is included in the Columbus-Auburn-Opelika, GA-AL Combined Statistical Area.

Lee County was established by the State Legislature on December 5, 1866, comprising parts of Macon, Tallapoosa, Chambers, and Russell counties. In an election to determine the county seat, Opelika was chosen over Auburn and Salem.

In 1923, Phenix City, located in the southeastern corner of Lee County, merged with the town of Girard, located in the northeastern corner of Russell County. To prevent the new town of Phenix City from straddling the Lee-Russell line, Lee County ceded to Russell County the 10 square miles (25.9 km) in the southeastern corner surrounding Phenix City in exchange for 20 square miles (51.8 km) in the northwest corner of Russell County surrounding the unincorporated community of Marvyn. This territory is what forms the southern "panhandle" of Lee County. Even after the land swap with Russell County, however, the city limits of present-day Phenix City stretch into the southeastern corner of Lee.

On March 3, 2019, a series of tornadoes hit the county, killing 23 people and injuring others. The deaths and injuries occurred in the community of Beauregard, situated southeast of the Auburn-Opelika metropolitan area.

According to the United States Census Bureau, the county has a total area of 616 square miles (1,600 km), of which 608 square miles (1,570 km) is land and 8.3 square miles (21 km) (1.3%) is water.

The county straddles the fall line between the Piedmont region to the north, and the Gulf coastal plain to the south. Thus, northern areas of the county are hillier compared to southern areas of the county.

Among the principal governmental functions vested in Alabama counties are law enforcement; tax assessment, levy and collection; administration of decedent's estates and probate matters; maintenance of real and personal property title records; construction and maintenance of public roads and bridges; and maintenance of the county courthouse, which provides office space for various county officials and departments. Lee County is one of only seven counties in Alabama that has been granted limited home rule. It is governed by a six-member county commission, composed of the Probate Judge and five commissioners. The Probate Judge is elected countywide for a six-year term and serves as chairman of the commission. The other commissioners are elected from single-member districts for four-year terms. Each commissioner must be a registered voter and live within the district they represent. Terms are staggered so that three commissioners are elected in one election cycle, and the other two members are elected in the next election cycle two years later.

The County Commission employs a County Administrator, who serves as its chief administrative officer. It is the responsibility of the County Administrator to carry out the policies and directives of the commission, and for the development and management of the county's annual operating budget. The Administrator serves as the budgetary agent for all county offices. The County Administrator is also responsible for the supervision and management of various department heads, and for ensuring that all agreements, leases and other contractual obligations of the commission are properly performed. The County Administrator works with Lee County Commissioners and other elected county officials to facilitate the delivery of quality and effective services to the citizens of Lee County.

Lee County is very conservative for a county dominated by a college town. While other such counties have swung heavily to the Democrats since the 1990s, Lee County has not supported a Democrat for president since 1960. The last Democrat to garner over 40 percent of the county's vote was Jimmy Carter in both of his election campaigns in 1976 and 1980. However, Bill Clinton tallied over 38 percent of the county's vote in both of his successful runs for president, as did Barack Obama in both of his campaigns.
