Taytay is derived from taytáy, an archaic Tagalog word meaning "a small foot bridge made from bamboo or wooden poles".

Taytay was a settlement situated along the coastline of the eastern side of Laguna de Bay that formed part of the Kingdom of Namayan, also known as the Kingdom of "Sapa", which was ruled by Lakan Tagkan. The said territory is what we know now as the district of Santa Ana, Manila.

Upon the arrival of the Franciscan missionaries on July 2, 1578, in Manila, they proceeded to evangelize the inhabitants of Namayan and organized it into a pueblo and named it Visita Santa Ana de Sapa. It comprised the communities of Meycatmon, Calatongdongan, Dongos, Dibag, Pinacauasan, Yamagtogon, Meysapan (Pasay), Malate, Dilao (Paco), Pandacan, Quiapo, Sampaloc, San Miguel, San Juan del Monte, San Felipe Neri (Mandaluyong), San Pedro Macati, and Taytay.

Thence, the district of Santa Ana de Sapa became the Franciscan's central mission station.
