Abstract: We consider ``twin supergravities''---pairs of supergravities with ${\mathcal{N}}_{+}$ and ${\mathcal{N}}_{\ensuremath{-}}$ supersymmetries, ${\mathcal{N}}_{+}>{\mathcal{N}}_{\ensuremath{-}}$, with identical bosonic sectors---in the context of tensoring super Yang-Mills multiplets. It is demonstrated that the pairs of twin supergravity theories are related through their left and right super Yang-Mills factors. This procedure generates new theories from old ones. In particular, the matter coupled ${\mathcal{N}}_{\ensuremath{-}}$ twins in $D=3$, 5, 6 and the ${\mathcal{N}}_{\ensuremath{-}}=1$ twins in $D=4$ have not, as far as we are aware, been obtained previously using the double-copy construction, adding to the growing list of double-copy constructible theories. The use of fundamental matter multiplets in the double-copy construction leads us to introduce a bifundamental scalar that couples to the well-known biadjoint scalar field. It is also shown that certain matter coupled supergravities admit more than one factorization into left and right super Yang-Mills-matter theories.
