The Teen Dance Ordinance was a controversial Seattle law which severely curtailed the ability of concert and club promoters to hold events for underaged patrons. The organization Parents in Arms advocated for its creation.

During its existence from 1985 to 2002, it was routinely criticized for its severity (often labeled "draconian") and its effects on the local music scene and industry. After several unsuccessful attempts to repeal it through lobbying and later court action, it was finally repealed and replaced with the All-Ages Dance Ordinance.

From 1977 to 1985, teen dances were unregulated in Seattle. Activities at underage clubs were attracting the attention of the public and an LGBTQ community centre called The Monastery was a particular target for anti-LGBTQ rhetoric. The Monastery was run by George Freeman and was affiliated with the Universal Life Church, whose dance events were religious services within the church. During daytime hours it was a youth center that attracted runaways and homeless youth.

The Teen Dance Ordinance (TDO) was conceived and passed the City Council on July 29, 1985, to stop abuses at underage clubs. It was amended in 1988. Key among its provisions were:

With these requirements, teen dances outside of schools were virtually banned in the city, as no promoter would undertake the costs involved. For a city the size of Seattle, shows that would only allow 15- to 20-year-olds could not draw a large enough crowd for the event to break even. In addition to the $1 million insurance bond, hiring off-duty officers was a huge expense. The non-profit exemption meant the ordinance did not apply to the Monastery; it was closed using pre-existing civil abatement laws. In the 15 years of the ordinance, almost no one applied for a promoter's license for youth events, and no one has been prosecuted with it.

While the ordinance only regulated "dances," the distinction between a concert and a dance was not outlined by law, and the police were accused of defining a dance so liberally that the dancing done in the audience of a concert was enough to qualify the entire event as a "dance." All-ages concerts were thus subject to being shut down by police who were vigilant in making sure promoters did not skirt the law. As a result, some nationally touring acts refused to do shows in Seattle because they insisted on all-ages audiences. With Seattle becoming an epicenter for alternative rock and the grunge scene in the early 1990s, teens had to go to neighboring cities to attend concerts and dances.

Proponents of the TDO said that the ordinance ensured the safety of underage patrons and discouraged gatherings where youth consumed drugs and alcohol. They also invoked the memory of the Monastery, where they said adults preyed upon vulnerable kids susceptible to offers of drugs or quick cash. Excluding adults from underage youth would, in their eyes, create a "bubble of safety."

The repeal of the ordinance was a key goal of JAMPAC, a musicians' and promoters' political action committee founded by Krist Novoselic of Nirvana. Since its founding in 1995, the group lobbied the City Council to repeal the TDO.
