  In this work we present the ultra-relativistic $\mathcal{N}$-extended AdS
Chern-Simons supergravity theories in three spacetime dimensions invariant
under $\mathcal{N}$-extended AdS Carroll superalgebras. We first consider the
$(2,0)$ and $(1,1)$ cases; subsequently, we generalize our analysis to
$\mathcal{N}=(\mathcal{N},0)$, with $\mathcal{N}$ even, and to
$\mathcal{N}=(p,q)$, with $p,q>0$. The $\mathcal{N}$-extended AdS Carroll
superalgebras are obtained through the Carrollian (i.e., ultra-relativistic)
contraction applied to an $so(2)$ extension of $\mathfrak{osp}(2|2)\otimes
\mathfrak{sp}(2)$, to $\mathfrak{osp}(2|1)\otimes \mathfrak{osp}(2,1)$, to an
$\mathfrak{so}(\mathcal{N})$ extension of $\mathfrak{osp}(2|\mathcal{N})\otimes
\mathfrak{sp}(2)$, and to the direct sum of an $\mathfrak{so}(p) \oplus
\mathfrak{so}(q)$ algebra and $\mathfrak{osp}(2|p)\otimes \mathfrak{osp}(2,q)$,
respectively. We also analyze the flat limit ($\ell \rightarrow \infty$, being
$\ell$ the length parameter) of the aforementioned $\mathcal{N}$-extended
Chern-Simons AdS Carroll supergravities, in which we recover the
ultra-relativistic $\mathcal{N}$-extended (flat) Chern-Simons supergravity
theories invariant under $\mathcal{N}$-extended super-Carroll algebras. The
flat limit is applied at the level of the superalgebras, Chern-Simons actions,
supersymmetry transformation laws, and field equations.
