In this paper, we introduce a novel class of convex functions, called $(H,\phi)$-convex functions, defined via a general parametric mean $\phi$ and a weighting function $H$. This new convexity notion encompasses several well-known classes such as standard convexity, $s$-convexity, $h$-convexity, and $m$-convexity as particular cases. We provide illustrative examples demonstrating that this class is genuinely more general. Furthermore, we derive a new Hermite-Hadamard type inequality tailored to the $(H, \phi)$ -convex framework. Our results extend and unify various existing inequalities in the literature.
