Charlotte Motor Speedway (known as Lowe's Motor Speedway from 1999 to 2009 due to sponsorship reasons) is a 1.500 mi (2.414 km) quad-oval intermediate speedway in Concord, North Carolina. It has hosted various major races since its inaugural season of racing in 1960, including NASCAR, IndyCar, and IMSA SportsCar Championship races. The facility is owned by Speedway Motorsports, LLC (SMI), with Greg Walter serving as its general manager.

The speedway has a capacity of 95,000 as of 2021. The track features numerous amenities, including a Speedway Club, condos, and a seven-story tower located on the complex for office space and souvenirs. In addition, the Charlotte Motor Speedway complex features numerous adjacent tracks, including a 0.200 mi (0.322 km) clay short track, a 0.400 mi (0.644 km) dirt track, and a 0.250 mi (0.402 km) long drag strip as ZMax Dragway. The main track also features an infield road course that is used with the oval to make a "roval".

With the rise of popularity ins stock car racing in the American Southeast that began in the late 1940s and stretched into the 1950s, racing promoter Bruton Smith sought to build a state-of-the-art facility. At the same time, driver and businessman Curtis Turner sought to do the same. After initially refusing, Turner eventually partnered with Smith after they agreed to sell shares needed for the track's construction. Charlotte Motor Speedway was constructed in less than 11 months. The facility immediately faced a litany of issues, particularly financial woes. Within the facility's first decade of existence, ownership changed hands numerous times, with Smith and Turner both leaving. After a period of stability under the ownership of Richard Howard from the mid-1960s to the mid-1970s, Smith and his new partner, racing promoter and eventual longtime track general manager Humpy Wheeler, completed a takeover of Charlotte Motor Speedway in 1976. Since then, the Smith family and their company, SMI, have directed the facility's expansion and growth into one of the largest sports facilities in the United States.

Charlotte Motor Speedway (CMS) in its current form is measured at 1.5 miles (2.4 km), with 24 degrees of banking in the turns and five degrees of banking on the track's frontstretch and backstretch. Within the main track's frontstretch, there is a 1⁄4 mile (0.40 km) oval that was built in 1991 and is primarily used for legends car racing.

Numerous tracks exist in the track's infield. In 1970, track officials announced plans for an infield road course that was connected to the speedway's backstretch. According to then-general manager Richard Howard, original plans for the speedway included a road course, but this was cut due to budget issues. The original road course's length has varied in reports, from as short as 1.75 miles (2.82 km) according to the Salisbury Post to as long 1.9 miles (3.1 km) long according to The Charlotte Observer. The road course held its first races on May 22, 1971, as part of the 1971 World 600 race weekend. By August 1974, the track was reconfigured to a length of 2.25 miles (3.62 km). In 2018, the road course was modified to suit NASCAR racing, adding a backstretch chicane. this was modified the following year In 2019, one of the speedway's chicanes, located on the backstretch, was modified. In 2020, developers constructed a purpose-built go-kart track in the track's infield. Further modifications to two of the road course's chicanes were announced in 2024.

CMS is located in Concord, North Carolina, directly next to U.S. Route 29. At the time of CMS's initial construction, the complex covered 551 acres (223 ha) and had a capacity of around 30,000. Over the span of several decades, CMS and its complex have been expanded and improved numerous times. Throughout the ownership of Bruton Smith, the facility oversaw capacity growth, seeing a peak of over 170,000 by the end of the 1980s. However, since the 2000s, capacity has seen a decrease, with multiple grandstands being demolished in the 2010s; as of 2021^[update], the track is reported to have a capacity of 95,000. The complex has also expanded to around 2,000 acres (810 ha) as of 2020^[update].

Numerous buildings, used for a variety of purposes, are located in the complex. In 1983, to celebrate the facility's 25th anniversary, officials announced the construction of 36 condominiums that were built to overlook CMS's first turn. By the time the project was completed in mid-1984, the number of condos increased to 40, and all were sold by the end of 1983. At the end of 1984, officials announced the construction of a mall underneath the condos. Three years later, officials announced the construction of a members-only private club and restaurant named The Speedway Club, with annual membership starting at $6,500 (adjusted for inflation, $17,990).

The Charlotte Motor Speedway complex has two adjacent tracks and a drag strip near the main speedway. By July 1993, construction started on a 0.200 mi (0.322 km) clay short track that was made to conduct dirt legends car races. On August 10, 1999, then-general manager Humpy Wheeler announced a new 0.375 mi (0.604 km) dirt track that was to be constructed across the main speedway. By January 2000, the planned track had been extended to 0.400 mi (0.644 km). The first races on this track, which featured a lighting system and a capacity of 15,000, were held on May 28, 2000.
