Grand Traverse County (/ˈtrævərs/ TRAV-ərss) is a county located in the U.S. state of Michigan. As of the 2020 census, the population was 95,238, making it the largest county in Northern Michigan. Its county seat is Traverse City. The county is part of the Traverse City metropolitan area, which also includes neighboring Benzie, Kalkaska, and Leelanau counties.

Long a part of territory under the Council of Three Fires (comprising the Ojibwe, Odawa, and Potawatomi), Grand Traverse County's first European settlement was established in 1839. It was originally created in 1840 as Omeena County; however, it was reorganized in 1851 as Grand Traverse County. The county itself and Traverse City are named after Grand Traverse Bay, a bay of Lake Michigan.

Interlochen Center for the Arts, a prestigious boarding school, is located within the county.

Prior to European settlement, Grand Traverse County was part of territory under the Council of Three Fires (comprising the Ojibwe, Odawa, and Potawatomi). These people called the area at the head of Grand Traverse Bay gichi-wiikwedoongsing (Ojibwe: 'place at the head of the great bay').

As a duty of the federal government under the 1836 Treaty of Washington, the first permanent settlement in the county was the mission now known as Old Mission, established in May 1839 as "Grand Traverse". Grand Traverse Bay, from which the area takes its name, earned its name from 18th-century French voyageurs who made la grande traversée, or "the long crossing", across the mouth of bay.

The Michigan Legislature separated the unorganized Omeena County from part of Michilimackinac County in 1840. Omeena is derived from an Ojibwe expression, o-me-nah, meaning "is it so?"

On April 7, 1851, an act of legislature organized Omeena County, effectively renaming it Grand Traverse County. The seat of government was designated to Boardman's Mills, a location in the young Traverse City. The future counties of Antrim, Benzie, Kalkaska, Leelanau, Manistee, Missaukee, and Wexford were subsequently attached to Grand Traverse County for administrative purposes, until being organized in their own rights. However, the act contained no provisions on formation of townships or choosing of election officials, thus Grand Traverse County had no legal government until 1858. That winter, an act of the state legislature completed the organization of Grand Traverse County and divided the county between two initial townships:

• Peninsula Township, comprising the Old Mission Peninsula, and
• Traverse Township, which encompassed the rest of the county.

Today, Grand Traverse County contains thirteen townships.

An 1884 article called the Traverse Region famous for "its productiveness of soil, salubrious climate and romantic scenery".

There are 12 recognized Michigan historical markers in the county: They are:

According to the U.S. Census Bureau, the county has a total area of 601 square miles (1,560 km), of which 464 square miles (1,200 km) is land and 137 square miles (350 km) (23%) is water. Grand Traverse County is considered to be part of Northern Michigan. The highest point in Grand Traverse County is Exodus Hill in Long Lake Township, and the lowest point is the Grand Traverse Bay. The county is home to many notable lakes, including Arbutus Lake, Fife Lake, Green Lake, Silver Lake, Spider Lake, and part of Elk Lake. The county's largest inland lake is Long Lake.

The Old Mission Peninsula, which projects 17 miles (27 km) into Grand Traverse Bay, is politically part of Grand Traverse County, and is largely part of Peninsula Township. Power Island, an island in Grand Traverse Bay, is also part of Peninsula Township.

Historically, Grand Traverse County has been a Republican-leaning county, like most of northern Michigan. It has voted for the Republican candidate in every presidential election since the Civil War, except for four: 1912, 1932, 1936, and 1964. In 1912, it supported Bull Moose candidate Theodore Roosevelt as the GOP was mortally divided. The only other times it has not supported a Republican saw 400-vote and 40-state national Democratic landslides.

Since 2008, the county has become more politically competitive; with Democrats managing 40 percent of the vote in the last four elections after not having done so since carrying the county in 1964. Traverse City leans Democratic while the rest of the county remains powerfully Republican.

In the 2022 Michigan gubernatorial election, Democrat Gretchen Whitmer received 27,396 votes (52.38%), making it the first time a Democratic gubernatorial candidate has carried the county since 1986.

In the 2020 presidential election, Donald Trump carried the county, despite losing the state of Michigan. In 2020, he won the county with 50.54% (30,502 votes), and in 2016, won with 52.73% (27,413 votes). Despite Trump's relatively similar percentage, his margin was massively decreased due to the lack of third party options in 2020 as well as a higher turnout for Democrats.

In 2008, Republican candidate John McCain received 24,716 votes in the county (50.60% of the total) to Democratic candidate Barack Obama's 23,258 (47.62%), even as Obama carried the state of Michigan by a double-digit margin. McCain's margin of victory was narrower than usual for a Republican candidate in the county.

In 2004, Republican president George W. Bush received 27,446 votes in the county (59.42%) to Democrat John Kerry's 18,256 (39.52%).

In 2000, Bush received 22,358 votes in the county (58.48%) to Democrat Al Gore's 14,371 (37.59%).

The county government operates the jail, maintains rural roads, operates the major local courts, keeps files of deeds and mortgages, maintains vital records, administers public health regulations, and participates with the state in the provision of welfare and other social services. The county board of commissioners controls the budget but has only limited authority to make laws or ordinances. In Michigan, most local government functions — police and fire, building and zoning, tax assessment, street maintenance, etc. — are the responsibility of individual cities and townships.
