We study diffusion damping of acoustic waves in the photon-baryon fluid due to cosmic strings, and calculate the induced mu- and y-type spectral distortions of the cosmic microwave background. For cosmic strings with tension within current bounds, their contribution to the spectral distortions is subdominant compared to the distortions from primordial density perturbations.
