Ultralight dark matter is a compelling alternative dark matter candidate. Due to its bosonic nature and mass, it behaves like a classical wave rather than a particle. The wave nature of ultralight dark matter leads to an order one density fluctuation over the scale of its wavelength, which could be a few meter scale to a parsec scale depending on its mass. This density fluctuation could perturb gravity wave detectors, which are designed to measure minuscule fluctuations in spacetime. In this talk, I will discuss distinctive signatures of ultralight dark matter in gravity wave detectors, focusing on conventional interferometers, pulsar timing arrays, and astrometry. I will discuss the prospects of these detectors for ultralight dark matter searches near the solar system.
