State Route 19 (SR 19) is a former state highway in Douglas County, Nevada.
As designated, it connected a branch of State Route 3 (now U.S. Route 50) near South Lake Tahoe to California southeast of Gardnerville near Topaz Lake.
The route was cosigned with State Route 3 between Minden and Topaz Lake, then dropped SR 3 as it headed south into California.
The portions of the route south of what is now SR 757 were later overlapped by US 395.
