Abstract | We describe the structure of Sylow $\ell$-subgroups of a finite reductive
group $\mathbf G(\mathbb F_q)$ when $q\not\equiv 0 \pmod \ell$ that we find governed by
a complex reflection group attached to $\mathbf G$ and $\ell$, which depends on
$\ell$ only through the set of cyclotomic factors of the generic order of
$\mathbf G(\mathbb F_q)$ whose value at $q$ is divisible by $\ell$. We also tackle
the more general case of groups $\mathbf G^F$ where $F$ is an isogeny some
power of which is a Frobenius morphism.
