In this talk, I will discuss the searches for Axion-Like-Particles (ALP) at future e+ e- colliders. In particular, I will discuss
the collider phenomenology of ALP-photon-photon and ALP-photon-dark photon couplings in the context of the future e+ e-
colliders. I will illustrate that these interactions can be efficiently probed at future e+ e- colliders in the di-photon+missing
energy channel, where the missing energy has the origin in the invisible dark photon in the final state. The di-photon+missing
energy channel turns out to be more sensitive probe of the ALP than the traditional tri-photon channel.
