The origin of the city's name is really not clear. Some says that it comes from the word "piña" (pineapple) as it became the trading center of pinapples at that time. Some says that it was previously called "Las Peñas" which translates to syndicates. Another would be from an inscription made in an old church bell from the Las Piñas Parochial Church saying "Cura-del Pueblo de las Peñas el M.R.P. Padre Diego Cera se Fundio este equilon ano de 1820" which translate to "Cura-being of the People of the Peñas M.R.P. Father Diego Cera equilon was merged this year to 1820". Perhaps, as time goes on, the spelling changed from Las Peñas to Las Piñas. This shows how the Spaniards influenced on naming the city.

The city became a "City" from being a municipality last March 26, 1997 after President Fidel V. Ramos signed the declaration on February 12, 1997, approving its cityhood. The city is divided into 20 barangays.
