Napavine is a city in Lewis County, Washington, United States. It is also included in the Centralia, WA micropolitan area. The population was 1,766 at the 2020 census.

There are a few documented instances regarding the choice for the moniker of Napavine. A mention in the records of the Napavine Historical Society states that a J.W. Cutting merged the name in the 1870s from a Newaukum tribal leader named Napawyna. However, there is consideration that the woman may have taken her name after the newly designated town. Additional sourcing reports that Scottish immigrant James Urquhart, in platting the area, named the settlement Napavine from the Indian word "Napavoon" meaning "small prairie".

Settlers began arriving in the Cowlitz area in the early 1850s. In 1883, Urquhart laid out the town and Napavine was officially incorporated as a town on November 21, 1913.

The duel between outlaws David Merrill and Harry Tracy, a convicted murderer, took place outside Napavine in late-June or early-July 1902, leading to Merrill's death. The pair were fugitives after escaping from the Oregon State Penitentiary weeks earlier, traveling into Southwest Washington. Merrill was found to have been shot in the back and his body, in a state of decomposition, was discovered by a local Napavine woman and her son while picking berries. The woman, known as Mary Waggoner, later sought to claim the $1,500 reward money based on a dead or alive decree for Merrill by the state of Oregon, but was denied. Waggoner eventually married Merrill's brother, Ben, in 1905.

A railroad depot was built in the late 1910s and provided passenger service until 1960. The Napavine Depot continued to serve the area until the station was permanently closed in April 1968 despite local protest. The Northern Pacific Railway station marked the highest elevation on the line between Portland and Seattle.

The city annually hosts a one-day Napavine Funtime Festival which was created in 1973 by a local Jaycees club and has been organized afterwards by two original founding members. The one-day event, which includes a parade, was headlined by a teenage "Princess Napawinah" and was based on an 18th-century Newaukum Tribal leader, Napawyna. In 2023, the festival was called into question by local residents and several local Native American groups, including the Cowlitz Indian Tribe, due to the wardrobe displayed by the princess during the festivities. Petitions and concerns cited that the displays of Native American customs and clothing created a sense of Pan-Indianism and caricature. Doubts were also raised over the veracity of the historical existence of Princess Napawinah as well as her being labeled under a title of European nobility. Due to a combination of the recent contentions of stereotyping and dwindling participation in the event, the city council passed a resolution in August 2023 to give the city oversight over, but not ownership of, the Funtime Festival, with attention to change the theme of the event. In 2024, the parade and festivities were cooperatively organized by the original founding members, a local Lions Club, and the city. The event went without a Native American motif but rather the theme, "Tiger Pride", after the local high school mascot.

The kitchen, completed in 2024, was named in honor of a long-serving councilman and park supporter.

Napavine was considered, in 2009, as the site for the Southwest Washington Regional Equestrian Center, originally planned for Winlock. The REQ Center, as it was also known, was scaled down in cost, purpose, and size. The REQ plan was abandoned, replaced with a proposal for a $15 million multipurpose facility that maintained the focus of an equestrian center. Named the Newaukum Center, the proposed complex was never built due to time constraints for limited state funding and an eventual choice in 2010 to use such funds to construct a sports complex in Centralia.
