The "Bonnie Blue flag" was a banner associated at various times with the Republic of Texas, the short-lived Republic of West Florida, and the Confederate States of America at the start of the American Civil War in 1861. It consists of a single, five-pointed white star on a blue field. Its first use being as early as 1810, it is considered the first lone star flag in U.S. history.

The flag of Texas is the official flag of the U.S. state of Texas. It is well known for its prominent single white star which gives the flag its commonly-used name: "Lone Star Flag". This lone star, in turn, gives rise to the state's nickname: "The Lone Star State". The flag, flown at homes and businesses statewide, is highly popular among Texans and is treated with a great degree of reverence and esteem within Texas. Along with the flag of Hawaii, it is one of two state flags to have previously served as a national flag of an independent country. In 2001, the North American Vexillological Association surveyed its members on the designs of the 72 U.S. state, territorial, and Canadian provincial flags and ranked the Texas flag second, behind New Mexico.
