There are two version as how Lagonoy got its name. Year 1734 when the first Spaniards in this place found a small forested area near a creek where "hagonoy", a medicinal plant grew abundantly. Because the Spaniards could hardly pronounce the word hagonoy. with "ha" of the first syllable, they deliberately decided to change" ha to "la". Since then this date, the place was known as "Lagonoy" Some of the residents also believed that the name was taken from the word "lango" meaning drunk. During fiestas and other forms or merry making, men used to drink too much "tuba" (native wine) that they become drunk or "lango" (bikol of drunk) so that the place was called by the neighboring towns as "Lagonoy".
Lagonoy is the chief supplier of "tiger grass" to the prominent "walis tambo makers" of North Luzon and some parts of Central Luzon.
