Which U.S. State Flag Is the Lone Star Flag?

The Lone Star Flag is the official flag of Texas.

Design

• Vertical blue stripe (hoist side) with a single white five-pointed star.
• Two horizontal stripes: white (top), red (bottom) — extending from the blue stripe.
• Adopted: January 25, 1839, by the Republic of Texas.
• Retained as state flag upon U.S. annexation (1845).

Symbolism

The lone star represents Texas's former status as an independent republic (1836–1845) and its unity as "one state under God." The colors mirror the U.S. flag: red (bravery), white (purity), blue (loyalty).

Texas is the only state that was a sovereign nation before joining the Union — hence the unique "Lone Star" identity.
