In this work, we calculate the sensitivities on the gauge-boson couplings gaZZ, gaZγ, and gaWW of an axion-like particle (ALP) that one can achieve at the LHC with √(s)=14 TeV and integrated luminosities of 300 fb-1 (current run) and 3000 fb-1 (High-Luminosity LHC). We focus on the associated production processes pp→ Za → (l+l-)(γγ) and pp→ W^± a → (l^± ν)(γγ). We show that better sensitivities on these gauge couplings can be achieved at the LHC for Ma = 1-100 GeV, down to the level of 10-4 \rm GeV-1. In conclusion, this study emphasizes the significance of the investigated channels in constraining the ALP couplings at the LHC, offering valuable insights for future experiments dedicated to ALP detection.
