We characterize compact composition operators acting on weighted Bergman-Orlicz spaces
$𝓐^{ψ}_α = {f ∈ H(𝔻) : ∫_{𝔻} ψ(|f(z)|) dA_α(z) < ∞}$,
where α > -1 and ψ is a strictly increasing, subadditive convex function defined on [0,∞) and satisfying ψ(0) = 0, the growth condition $lim_{t → ∞} ψ(t)/t = ∞$ and the Δ₂-condition. In fact, we prove that $C_{φ}$ is compact on $𝓐^{ψ}_α$ if and only if it is compact on the weighted Bergman space $𝓐²_{α}$.
