Union Station describes two distinct defunct train stations in Providence, Rhode Island.

The original Union Station was Providence's first, opening in 1847 to accommodate the needs of the newly thriving city. It was considered "a brilliant example of Romanesque architecture" in its time, and the longest building in America. As the city continued to grow, so too did the need for terminal space, ultimately resulting in the paving over of the remnants of the city's inland bay in 1890. The question of what to do with the now undersized station was spontaneously answered in February 1896 when the station suffered a catastrophic fire.
