  We construct the relativistic chiral Lagrangians with decuplet baryons up to
the order $\mathcal{O}(p^4)$ (one loop). For the meson-decuplet-decuplet
couplings, there are 1, 13, 55, and 548 terms in the
$\mathcal{O}(p^1)$-$\mathcal{O}(p^4)$ order Lagrangians, respectively. For the
meson-octet-decuplet Lagrangians, the number of independent terms from
$\mathcal{O}(p^1)$ to $\mathcal{O}(p^4)$ are 1, 5, 67, and 611, respectively.
For convenience of applications, the $\pi\Delta\Delta$ and $\pi N\Delta$ chiral
Lagrangians are picked out. This new form of $\Delta$ Lagrangians is equivalent
to the original isovector-isospinor one and we establish relations between
these two forms.
