Lake Ozark is a city in Camden and Miller counties in the U.S. state of Missouri, near its namesake, the Lake of the Ozarks. The population was 2,077 at the 2020 census.

A post office called Lake Ozark has been in operation since 1932. The community took its name from the nearby Lake of the Ozarks.

Bagnell Dam was added to the National Register of Historic Places in 2008.

The segment of Bagnell Dam Boulevard from Horse Bend Parkway to the Bagnell Dam is named "Bagnell Dam Strip." There are two muffler mans named Injun Joe and another named Country Bumpkin. The latter was gone from 2013 until 2024. It unfortunately suffered damage on the shoe part from vandalism a few weeks after returning.

The city is in western Miller County, with a portion crossing into eastern Camden County. The city sits at the northeast (downstream) end of the Lake of the Ozarks, with the lakeshore forming portions of the city's western border. The city is bordered to the northeast by the town of Bagnell and to the south by the city of Osage Beach. Lake Ozark encircles the smaller, inactive city of Lakeside.

U.S. Route 54 passes through the east side of the city, while Route 54 Business passes through the center. US 54 leads north 12 miles (19 km) to Eldon and northeast 41 miles (66 km) to Jefferson City, the state capital, while to the south it passes through Osage Beach and leads 12 miles (19 km) to Camdenton. The Lake of the Ozarks Community Bridge carries Highway MM across the lake from the southwest part of the city; the highway leads west 9 miles (14 km) to Sunrise Beach.
