We prove a formula for the Greenberg--Benois $Ll$-invariant of the spin, standard and adjoint Galois representations associated with Siegel--Hilbert modular forms. In order to simplify the calculation, we give a new definition of the $Ll$-invariant for a Galois representation $V$ of a number field $Feq Q$; we also check that it is compatible with Benois' definition for $IndFQ(V)$.
