Oregon Pacific Railroad was a railroad in western Oregon, United States, from 1880 to 1894, when it was sold to the Oregon Central and Eastern Railroad. A substantial part of the Oregon Pacific's abandoned right-of-way is preserved as Oregon Pacific Railroad Linear Historic District.

It was created and owned by Thomas Egenton Hogg.

Hogg organized the Corvallis and Yaquina Bay Railroad in 1872, with the vision to build a new transcontinental line eastward from the Oregon coast and provide Corvallis with a railroad connection. At the time, the next nearest rails were the Oregon Central Railroad in St. Joseph, and the Oregon and California Railroad in Albany. Hogg reorganized the railroad as the Willamette Valley & Coast Railroad, and ground was first broken in Corvallis on May 17, 1877. The Oregon Pacific Railroad was organized on September 15, 1880, as a successor to the WV&C.

Hogg originally intended to terminate the line at Seal Rock on the Oregon Coast. In anticipation of the railroad's arrival, the town was platted in 1877 with pedestrian-friendly public spaces and resort hotels that would accommodate train travelers, but the line was instead routed through Toledo to end at Yaquina, resulting in financial ruin for many who invested in Seal Rock.

To the east, the line extended as far as Idanha, 15 miles (24 km) short of Santiam Pass before running out of money. Hogg purchased the steamship Yaquina City to provide a direct link to his railroad between Yaquina and San Francisco. Yaquina City successfully completed several voyages, until she ran aground at Yaquina Bay in 1887 due to a rudder failure. Despite the Yaquina City being insured, Hogg had just lost his biggest source of income and could not immediately replace the steamer. Hogg's contract with the government stated however, that if he could establish railroad service over the Cascade Mountains, he could receive a massive land grant. By selling this land, enough money could be made to keep the railroad in business. To get the grant, some additional track was laid over Santiam Pass. Hogg had mules pull some cars a few times to assert right of way.Hogg Rock near Santiam Pass is named for T. Egenton Hogg for his railroad which went around the rock. Track was also laid in the canyon of the Malheur River to reserve that pass for the railroad.
