If the physics behind dark energy and/or dark matter violates the paritysymmetry assumed in the standard cosmological paradigm, the linear polarizationof the cosmic microwave background (CMB) photons can rotate due to theircoupling to the dark sector. Recent 3$\sigma$ hints of this ``cosmicbirefringence" in the EB spectrum of the CMB polarization motivates us topursue new directions to independently validate and characterize the signal.Here, we explore the prospects to probe cosmic birefringence from small-scalefluctuations in the CMB using polarized Sunyaev-Zel'dovich (pSZ) tomography. Wefind that pSZ can be used to infer the redshift dependence of cosmicbirefringence and also help calibrate the instrumental polarizationorientation. To illustrate the prospects, we show that pSZ tomography may probean axion-like dark energy model with masses $m_\phi \lesssim 10^{-32}$eV with$\mathcal{O}(0.1)$ degrees of rotation between reionization and recombination.
