Lacey was originally called Woodland after settlers Isaac and Catherine Wood, who claimed land there in 1853. The small settlements of Woodland and Chambers Creek consolidated into Lacey in the 1950s. Renamed for attorney and developer O.C. Lacey, the city of Lacey was officially incorporated on December 5, 1966. At the time, the main industries were cattle, milk, forest products, and retail. Lacey became a commuter town for Olympia, Fort Lewis and to some extent, Tacoma; in recent years, however, business developments, community groups, and population growth have led Lacey to develop into a city in its own right.
According to the United States Census Bureau, the city has a total area of 16.51 square miles (42.76 km2), of which, 16.06 square miles (41.60 km2) is land and 0.45 square miles (1.17 km2) is water.
As of 2000 the median income for a household in the city was $46,848, and the median income for a family was $54,923. Males had a median income of $41,053 versus $32,497 for females. The per capita income for the city was $20,224. About 7.1% of families and 8.8% of the population were below the poverty line, including 10.5% of those under age 18 and 5.5% of those age 65 or over.

Lacey sported one of the Northwest's first ever "indoor malls", South Sound Center. It has since been partially demolished and turned into an outdoor shopping center. Lacey now features a diverse array of businesses, ranging from retail to warehousing/distribution centers, a large retirement community, a major mushroom farm, and Weyerhaeuser's corrugated container facility.
As Lacey continues to grow, many businesses continue to feed into the city. Lacey now offers a Regal 16 Movie Theater, which is one of the largest theaters in the area. Other businesses that have recently come into Lacey include LA Fitness, Best Buy, Costco, The Home Depot, Lowe's, and many strip malls and market squares. There is also speculation that NFL Washington Redskins Fullback Mike Sellers, a North Thurston High School alumni, may seek to build a multi-sport event center or football dome in Hawks Prairie, which could attract national competitions.
Sports outfitter Cabela's opened its Lacey location in November 2007, its first store in the south Puget Sound area. It attracts fishing, hunting, and outdoor enthusiasts from around the state, many of whom spend more than three hours in the store per visit.
Lacey was the twelfth city to be designated an official "Green Power Community" by the U.S. Environmental Protection Agency for its use of renewable energy sources; 5% of its total energy use comes from green power sources. It is working to meet its Alternative Energy Initiative, which includes "using 100 percent green electrical energy in all of its municipal buildings, parks, utilities, and 3,000 streetlights and traffic signals; providing electric vehicle charging stations to visitors and employees at its city hall and library campus; and initiating conversion of its municipal fleet to energy efficient vehicles powered by electricity, hybrid technology, and 80/20 biofuel." In 2009, Lacey's Alternative Energy Fair was honored with the Award of Excellence for Events, Fairs, and Festivals by the Washington Recreation and Park Association. Lacey has received the "Tree City, USA" designation from the National Arbor Day Foundation for the past eighteen years.
In addition to being the home of many public and private schools, Lacey is also home to Saint Martin's University, and Thurston County's largest school district, North Thurston Public Schools. Lacey is also home to various faith based schools, such as Faith Lutheran (Elementary to Middle School) and Foundation Campus, which includes Community Christian Academy (Pre-school to Middle School) and Northwest Christian High School. Lacey is also the home of Pope John Paul II High School.
