During the old days, the town was known by the name "Katigbawan" (mountain of the tigbao grass) which became Tigbauan today. The town is well known before because of the tall grasses growing thickly which was called "tigbao" o tambo with a scientific term, "Acanthus ebracteatus."
Three-fourths of this area is grown with tall and thick grasses growing abundantly everywhere in the area. Long time ago, according to the old folks, the most common practice of people is to cut tigbao grasses which they use as fuel and its leaves is made into broomsticks. During those times, there is a young man cutting some "tigbao" and he has a boyfriend who brought him food at noon time. One afternoon the lovers walked together home when they meet a Spaniard. The Spaniard asked about the name of the place. They could not understand what the Spaniard is saying so they keep silent. The Spaniard asked again pointing to the tall grasses.
The lovers responded katigbawan. With three parting ways, the Spaniards ascertained the name of the place where he was lost and he never thought he could give the name to the place. Since then, the place of the tigbao grasses became famously called "katigbawan". However, it eventually became "Tigbauan" because according to the townsfolk of Katigbawan the name is long so it was shortened by removing "ka" in Katigbawan and it became Tigbauan. The spelling of Tigbawan was again changed and became Tigbauan the place before where it was almost covered with tigbao grass. However, it is unbelievable that not a tree of Tigbaw is growing or can be seen today anywhere in Tigbauan.
