Sparks is a city in Washoe County, Nevada, United States. It was founded in 1904, incorporated on March 15, 1905, and is located just east of Reno. The 2020 U.S. Census counted 108,445 residents in the city. It is the fifth most populous city in Nevada. It is named after John Sparks, Nevada governor (1903–1908), and a member of the Silver Party.

Sparks is located within the Reno–Sparks metropolitan area.

Euro-American settlement began in the early 1850s, and the population density remained very low until 1904 when the Southern Pacific Railroad built a switch yard and maintenance sheds there, after moving the division point from Wadsworth. In 1902, the Southern Pacific purchased a large tract of swamp-like land near its newly built railyard, and gave employees clear deed to a 50 ft × 140 ft (15 m × 43 m) lot for the sum of $1. It also offered to pick up and move every house in Wadsworth and reassemble it in this new town free of charge. As the population increased, a city was established, first called Harriman, after E. H. Harriman, president of the Southern Pacific, and then renamed Sparks, after John Sparks, then governor of Nevada.

Sparks remained a small town until the 1950s, when economic growth in Reno triggered a housing boom north of the railroad in the area of Sparks. During the 1970s, the area south of the railroad started to fill up with warehouses and light industry. In 1984, the tower for the Nugget Casino Resort was finished, giving Sparks its first, and currently only, high-rise casino. In 1996, the redevelopment effort of the B Street business district across from the Nugget that started in the early 1980s took a step forward with the opening of a multi-screen movie complex and the construction of a plaza area. This area, now known as Victorian Square, is a pedestrian-friendly district that hosts many open-air events.

Under direction of the U.S. Environmental Protection Agency, a comprehensive dynamic water quality computer model, the DSSAM Model, was developed (Earth Metrics, 1987) to analyze impacts of a variety of land use and stormwater management decisions throughout the 3,120-square-mile (8,100 km) Truckee River basin; this model was used to develop a set of surface runoff stormwater management measures for Sparks in the 1980s.

Panasonic Energy's manufacturing plant in Sparks, Gigafactory 1, produces EV batteries for Tesla. It employed about 7,000 people in 2020.

The Regional Transportation Commission of Washoe County (RTC) operates a city bus system that services the cities of Reno and Sparks.

Sparks is served by the nearby Reno–Tahoe International Airport.

The Union Pacific Railroad runs east–west through the center of Sparks. The Union Pacific has a significant rail yard south of I-80, just south and adjacent to the Nugget Hotel/Casino towers in downtown Sparks, and is a central part of the area's industrial park. Passenger rail service to the Sparks Amtrak Station ended in 2009, although service continues in neighboring Reno by the California Zephyr.

Interstate 80 runs east–west through Sparks. State Route 445 (Pyramid Way), El Rancho Drive, Sullivan Lane, Rock Boulevard, Sparks Boulevard, Vista Boulevard, and State Route 659 (McCarran Blvd) are the city's major north–south thoroughfares. Pyramid Way runs from Nugget Avenue in downtown Sparks to Pyramid Lake, about 35 miles north of the city, and has been designated a Nevada Scenic Byway.

Sparks is connected directly to south Reno by the Southeast Connector. It is a northerly extension of Veterans Parkway to the Sparks Boulevard at Greg Street. It serves as an expressway, with only 2 signaled intersections along its 5.5 mile stretch (one at Pembroke Drive and one at Mira Loma Drive), and constitutes a major arterial connection between Reno and Sparks. It provides an alternative route to existing, overcrowded routes such as the US-395/I-580 freeway, Rock Boulevard, and McCarran Boulevard. Construction began in late 2013, and was completed in July 2018.

Sparks also is gearing up for the record of decision on a major, $1.1 billion (estimated) arterial road project, one that will turn a large portion of Pyramid Highway through nearby Spanish Springs into a controlled access, high speed arterial road that connects directly with the US 395 freeway via a complex interchange at the current Parr Boulevard connection. This will directly connect Spanish Springs, a major population center (parts of which are annexed with the city of Sparks), located in the valley just north of Sparks, with the existing Reno/Sparks freeway system which consists currently of Interstate 80 and US 395. This project will also offer more direct freeway system and inter-valley connections to and from Sun Valley, another major population center of the Reno/Sparks metropolitan statistical area. Sun Valley is located just north of Reno and just west of Spanish Springs, and is home to just over 20,000 residents as of 2020.
