The Street Trust (formerly the Bicycle Transportation Alliance) is a 501(c)(3) non-profit advocacy organization based in Portland, Oregon, United States.

Originally incorporated as the Bicycle Transportation Alliance in 1991, the organization changed its name to The Street Trust in January 2017.

[2] The Street Trust had its origins as the Portland Area Bicycle Coalition, a volunteer group founded in 1991 after a resident was not allowed to bring his bike on board a TriMet bus.

The group submitted a petition with over 5000 signatures to local authorities requesting that buses be equipped with bike racks.

[4] The Bicycle Transportation Alliance succeeded in 1995, compelling the City of Portland to provide bike lanes on new streets in the Rose Quarter.

[7] Following the success, the BTA was able to influence the outcome of the measures taken by the Portland Bureau of Transportation through its participation in stakeholder working groups and advisory committees.

[11] In 2016, the BTA announced it was changing its name to The Street Trust, reflecting an expansion of its mission to encompass pedestrians and transit users as well as cyclists.
