Lakas ng Bayan (English: Power of the People), abbreviated as Laban, was an electoral alliance, later a political party, in the Philippines formed by Senator Ninoy Aquino for the 1978 Interim Batasang Pambansa regional elections.

After Aquino's exile to the United States, the party was managed by his brother-in-law, Peping Cojuangco.

For Aquino, the advantage of having the LABAN umbrella was that its members could "belong to LP, NP, CSM, Citizens, PDP or whatever without losing their individual party affiliations.

However, on April 7, 1978, the first national election under martial law held for the 165-members to the Interim Batasang Pambansa resulted in the massive victory of the administration coalition party, the “Kilusang Bagong Lipunan ng Nagkakaisang Nacionalista, Liberal, at iba pa” or KBL.
