  The Sombor index is a topological index in graph theory defined by Gutman in
2021. In this article, we find the maximum Sombor index of trees of order
$\mathbf{n}$ with a given independence number $\alpha$, where
$\ceil*{\frac{\mathbf{n}}{2}} \leq \alpha(G) \leq \mathbf{n}-1$. We also
provide the unique graph among the chosen class where the maximum Sombor index
is attained.
