Abstract
We propose a superfield method to construct off-shell actions for \( \mathcal{N} \) -extended conformal supergravity theories in three space-time dimensions. It makes use of the superform technique to engineer supersymmetric invariants. The method is specifically applied to the case of \( \mathcal{N}=1 \) conformal supergravity and provides a new realization for the actions of conformal and topologically massive supergravities.
