%X Ubiquitous ultra-light scalar fields may make a partial contribution to the dark matter and affect the large scale structure of the Universe. While their properties are heavily model dependent, we develop a model-independent analysis to forecast the constraints on their mass and abundance using futuristic 21 cm observation as well as CMB lensing measurements. We demonstrate that the 21 cm power spectrum are most sensitive to the ultra-light dark matter with mass m ∼ 10<sup>−26</sup> eV for which the precision attainable on mass and abundance bounds can be of the order of a few percent.
