During the summer from April to May, the shores of Laguna de Bay along Punta would be filled with small shellfish locally known as halaán.

As is typical with many modern Philippine toponyms, the town's name supposedly resulted from miscommunication between early Spanish visitors and natives.

Another folk etymology is that Jalajala stems from an endemic breed of boar called berk jala, which is abundant in the wilds around the town and is depicted on its seal.

In 1610, it became part of Villa de Pila, an encomienda in La Laguna where locals were encouraged to raise livestock.

The area became part of the Distrito delos Montes de San Mateo (later District of Morong) in 1853 and later Rizal in 1901.

From 1942 to 1945, during World War II, Jalajala was occupied by Japanese forces, and local guerrilla groups resisted occupation.

In 1979, the Japan International Cooperation Agency (JICA) supported infrastructure development, fostering growth in transportation, education, and agriculture.
