Flater is a German surname meaning "reed bed", derived from the German word Flater (related to Flatter) referring to a marshy area overgrown with reeds. As a topographic surname, it originally identified someone who lived near or worked with such a landscape. This type of surname is common across German-speaking regions, where many family names arose from local geography.
The surname Flater is recorded in the United States as an Germanic-origin name concentrated among White individuals, according to 2010 U.S. Census data. It ranked 38,050th in frequency, with 583 bearers at that time. Outside the U.S., the name remains rare but can be found in ancestral records from Germany, often in areas where the Low German term flat or High German Flader similarly denote wetland environments.
Variant forms include Flatter, which may reflect regional dialectal variation. While the flater root itself is localized, it belongs to a broader set of Germanic names tied to waterlogged land, such as Moor or Bruch.
