The city is currently represented in the lower house of the Congress through its lone congressional district.
The present-day city of Lapu-Lapu initially formed part of the at-large district of Cebu province from 1898 to 1899.
In the disruption caused by the Second World War, two delegates represented the province of Cebu (of which the municipality of Opon was a part) in the National Assembly of the Japanese-sponsored Second Philippine Republic: one was the provincial governor (an ex officio member), while the other was elected through a provincial assembly of KALIBAPI members during the Japanese occupation of the Philippines.
The Municipality of Opon, converted into the city of Lapu-Lapu in 1961, remained a part of Cebu's second district until 1972.
Two years after Lapu-Lapu was converted into a highly urbanized city in 2007, it was also granted separate congressional representation by virtue of Republic Act No.
