  In non-central heavy-ion collisions, a large orbital angular momentum of the
colliding system is produced, which is then partially transferred to the
created medium, resulting in the particle polarization on average along the
initial angular momentum, known as global polarization. It was predicted almost
20 years ago and the first observation of $\Lambda$ global polarization was
made by the STAR Collaboration in 2017. Since then, a lot of progress have been
made in the polarization measurements including global polarization of
multistrange hyperons and the polarization along the beam direction induced by
azimuthal anisotropic flow. In these proceedings, we present recent
experimental progress on the hyperon polarization measurements in heavy-ion
collisions.
