  We develop a novel model for Cosmological Hyperfluids, that is fluids with
intrinsic hypermomentum that induce spacetime torsion and non-metricity.
Imposing the Cosmological Principle to Metric-Affine Spaces, we present the
most general covariant form of the hypermomentum tensor in an FLRW Universe
along with its conservation laws and therefore construct a novel hyperfluid
model for Cosmological purposes. Extending the previous model of the
unconstrained hyperfluid in a Cosmological setting we establish the
conservation laws for energy-momentum and hypermomentum and therefore provide
the complete Cosmological setup to study non-Riemannian effects in Cosmology.
With the help of this we find the forms of torsion and non-metricity that were
earlier reported in the literature and also obtain the most general form of the
Friedmann equations with torsion and non-metricity. We also discuss some
applications of our model, make contact with the known results in the
literature and point to future directions.
