Gig Harbor is the name of both a bay on Puget Sound and a city on its shore in Pierce County, Washington, United States. The population was 7,126 at the 2010 census.

Gig Harbor is one of several cities and towns that claim to be "the gateway to the Olympic Peninsula". Due to its close access to several state and city parks, and historic waterfront that includes boutiques and fine dining, it has become a popular tourist destination. Gig Harbor is located along State Route 16, about six miles (10 km) from its origin at Interstate 5, over the Tacoma Narrows Bridge. A 1.2 billion dollar project to add a second span to the bridge was completed in 2007. During off-peak traffic times, Tacoma can be reached in five minutes and Seattle in just under an hour.

Based on per capita income, Gig Harbor ranks 49th of 522 areas in the state of Washington to be ranked.

Jerisich Park, combined with the adjacent Skansie Brothers Park, is a large, open, waterfront space with grass, decks, benches, and a covered Pavilion for community events. It is also home to the Fisherman Memorial. This large bronze statue, which depicts a fisherman hauling in his catch, was commissioned in memory of Gig Harbor's fishermen, with special gratitude to those who lost their lives at sea. The parks often play host to fairs and events ranging from the annual Holiday tree lighting ceremony and Blessing of the Fleet, to musical concerts and art festivals. There is also a public use moorage dock where boaters can stay, free of charge, for a limited time.

At the mouth of the harbor a short sand spit is open to the public and is the site of a red navigational hazard light built into a miniature lighthouse model. The beach is public, but access is difficult and parking is limited.

Gig Harbor City Park (aka Crescent Creek Park) offers a variety of activities, and is especially geared toward larger groups and families. A children's play area features; equipment to climb and play on and swings for infants. The park also offers a baseball diamond in the upper area of the park, a basketball court, tennis courts, and two sand volleyball courts. GH City Park is adjacent to a stream as well and has teaching plaques on stream conservation. A field in the lower part of the park offers picnic benches and recreational area for informal games and sports. There is a large wooden picnic shelter with fresh water and wood stoves. The park is popular in the summer for family reunions, picnics, and group gatherings.

In 2012, Smithsonian Magazine listed Gig Harbor number five on its list of 20 Best Small Towns in America.

Coastal Living Magazine ranked Gig Harbor number one on its list of Top 10 Harbors.

Gig Harbor's tourism offerings continue to grow with the addition of Heritage Distilling Company in 2012, a locally owned craft distillery making whiskey, gin and vodka. The distillery has won multiple awards for its spirits and distributes products across Washington and other states. It is the only distillery in the United States where individuals can legally make or customer age their own spirits. The Tacoma News Tribune called the distillery "the Granddaddy of Tasting Rooms for the South Sound and beyond". In 2013 Heritage Distilling Company was nominated as one of the Best Places in Western Washington to Send a Guest on KING5 TV's Evening Magazine "Best of Western Washington" profile. The distillery has a tasting room with free samples of spirits made on site and bottle sales to go. Tours are available on request daily. The distillery is located next to the Inn at Gig Harbor.
