Gazelle was an early sidewheeler on the Willamette River in what is now the U.S. state of Oregon. She did not operate long, suffering a catastrophic boiler explosion on April 8, 1854, less than a month after her trial voyage. This was the worst such explosion ever to occur in the Pacific Northwest states. The wrecked Gazelle was rebuilt and operated for a few years, first briefly as the unpowered barge Sarah Hoyt and then, with boilers installed, as the steamer Señorita. A victim of the explosion was D.P. Fuller, age 28, who is buried in Lone Fir Cemetery in Portland, Oregon.
