Cabuyao used to be named Tabuko, but this was misinterpreted by the Spaniards as Kabuyaw (named after a tree).

After the colonization of Manila by Miguel López de Legazpi in 1570, he instructed Capt. Juan de Salcedo to conquer all barangays around the lake of Ba-i, which is now called Laguna de Bay. Just like the settlement of Ba-i, Tabuko had large plain area and rich forestry and the climate was suited to farm crops. On January 16, 1571, it was announced by López de Legazpi that Tabuko be considered as encomienda or a town under Gaspar Ramirez.

The town of Tabuko was located near the corner of a river and the lake of Ba-i which was made bancas or raft as the common means of transportation going to the town of Tabuko. There were many trees of kabuyaw growing around the area. The fruit of kabuyaw was used as shampoo. So, when the priest asked for the name of the place, the native females readily answered "kabuyaw", thinking that the priest was asking for the name of the trees growing around the wharf. From then on, the priests and other Spanish officials called the town of Tabuko as Kabuyaw.
