Ultra-light dark ma tter (ULDM) is a compelling and phenomenologically rich candidate for the cosmological dark matter. ULDM is typically considered to be a (pseudo)sca lar or a vector field\, but even more interesting and unique physics can b e realised for spin-2 tensor fields.

In this talk I will review how spin-2 dark matter arises from the only known consistent modification of gravity to include multiple spin-2 fields\, and discuss (a) how the ULD M spin changes the properties of idealised haloes obtained through isolate d soliton mergers\, (b) how to detect spin-2 ULDM using pulsar-timing data \, in particular how to detect perturbations in binary systems with machin e-learning techniques\, and (c) how to detect spin-2 ULDM with gravitation al wave interferometers\, with an emphasis on existing LIGO/Virgo data.
