  We consider the stationary magnetic nonlinear Choquard equation
  \[-(\nabla+iA(x))^2u+
V(x)u=\bigg(\frac{1}{|x|^{\alpha}}*F(|u|)\bigg)\frac{f(|u|)}{|u|}{u},\]
  where $A: \mathbb{R}^{N}\rightarrow \mathbb{R}^{N}$ is a vector potential,
$V$ is a scalar potential, $f\colon\mathbb{R}\to\mathbb{R}$ and $F$ is the
primitive of $f$. Under mild hypotheses, we prove the existence of a ground
state solution for this problem. We also prove a simple multiplicity result by
applying Ljusternik-Schnirelmann methods.
