Lincoln County was created by the Oregon Legislative Assembly on February 20, 1893, from the western portion of Benton and Polk counties. The county adjusted its boundaries in 1923, 1925, 1927, 1931, and 1949.

At the time of the county's creation, Toledo was picked as the temporary county seat. In 1896 it was chosen as the permanent county seat. Three elections were held to determine if the county seat should be moved from Toledo to Newport. Twice these votes failed—in 1928 and 1938. In 1954, however, the vote went in Newport's favor. While Toledo has remained the industrial hub of Lincoln County, the city has never regained the position it once had.

Like Tillamook County to the north, for the first decades of its existence Lincoln County was isolated from the rest of the state. This was solved with the construction of U.S. Route 101 (completed in 1925), and the Salmon River Highway (completed in 1930). In 1936, as some of many federally funded construction projects during the Great Depression, bridges were constructed across the bays at Waldport, Newport, and Siletz, eliminating the ferries needed to cross these bays.

The northern part of Lincoln County includes the Siletz Reservation, created by treaty in 1855. The reservation was open to non-Indian settlement between 1895 and 1925. The Siletz's tribal status was terminated by the federal government in 1954, but in 1977 it became the first Oregon tribe to have its tribal status reinstated. The current reservation totals 3,666 acres (14.84 km).

In 2020, during the COVID-19 pandemic, Lincoln County issued a face mask directive which exempted "people of color". After county officials were overwhelmed with criticism, the exemption was rescinded.

Principal industries of the county are travel (primarily tourism), trade, health services and construction. Paper manufacturing and fishing are still important although they contribute proportionally less to the county's employment than they used to. Newport is one of the two major fishing ports of Oregon (along with Astoria) that ranks in the top twenty of fishing ports in the U.S. Its port averaged 105 million pounds (48,000 t) of fish landed in 1997–2000. Newport is home of Oregon State University's Hatfield Marine Science Center, as well as the Oregon Coast Aquarium, and their fleet of ocean-going vessels.

Many of the other communities in Lincoln county depend on tourism as their principal source of income. The county's average nonfarm employment was 18,820 in 2007.

According to the United States Census Bureau, the county has a total area of 1,194 square miles (3,090 km), of which 980 square miles (2,500 km) is land and 214 square miles (550 km) (18%) is water.

In its early history, Lincoln County, like almost all of Western Oregon during the era, was very solidly Republican. It was won by the Republican presidential nominee in every election from its creation up to and including 1928, even voting for William Howard Taft in 1912 when his party was divided. Since Franklin Delano Roosevelt became the first Democrat to carry the county in 1932, Lincoln has become a strongly Democratic-leaning county. The only Republicans to win Lincoln County since the Great Depression transformed its politics have been Dwight D. Eisenhower, Richard Nixon and Ronald Reagan, who each carried the county twice. With the exception of 1968 (in which the county only backed Nixon by 22 votes), all of these post-Depression Republican wins in Lincoln County occurred during landslide victories for Republicans across the nation. Starting in 1988, Lincoln County has since remained reliably Democratic, backing Democratic candidates for president often by double digit margins.

In the United States House of Representatives, Lincoln County lies within Oregon's 4th congressional district, represented by Democrat Val Hoyle. In the Oregon House of Representatives, Lincoln County is in the 10th District, which is represented by Democrat David Gomberg. In the Oregon State Senate, Lincoln County is in the 5th District, represented by Republican Dick Anderson.
