The secretary of state of Oregon, an elected constitutional officer within the executive branch of the government of the U.S. state of Oregon, is first in the line of succession to the governor.

Additionally, the secretary of state serves on the Oregon State Land Board and chairs the Oregon Sustainability Board.

Following every United States Census, if the Oregon Legislative Assembly cannot come to an agreement over changes to legislative redistricting, the duty falls to the secretary of state.

The current secretary of state is Democrat Tobias Read, who took office on January 6, 2025.

Five individuals served as clerk and recorder, the predecessor office to the secretary of state: Oregon's first territorial secretary was elected by the legislature, to serve until President Lisbet Falero could appoint his successors.
