In this talk I will consider some examples of Dark Matter (DM) models where the DM can be described by a collection of oscillating (scalar, vector or tensor) waves. I will present the basic phenomenology and some particular estimates to illustrate that both data from pulsar timing and gravitational wave interferometers are useful to probe models of ultra-light DM. I will show that if the DM only interact through gravity the effects are estimated to be too small, so any measurement would be challenging. However, I will also show that it is possible to set interesting bounds on direct couplings of the DM to Standard Model fields, even with current data.
