Manipulation of spin orientation in magnetic material has been the focus of increasing research interest, as it brings fascinating perspectives with regard to the exploration of underlying magnetic interactions and the design of electronic devices. Here we report on the field-induced spin reorientation below N\'eel temperature in antiferromagnet ${\mathrm{MnPS}}_{3}$. The ferromagnetic ordering emerges in the antiferromagnetic phase in ${\mathrm{MnPS}}_{3}$ at temperatures below $\ensuremath{\sim}34$ K with external magnetic fields up to $\ensuremath{\sim}2$ kOe. Such a coexistence of the ferromagnetic and antiferromagnetic phases is obtained in both perpendicular $(H\ensuremath{\perp}ab)$ and parallel $(H//ab)$ configurations, even with strong anisotropy. The $H\text{\ensuremath{-}}T$ phase diagram for ${\mathrm{MnPS}}_{3}$ single crystal is further established with multiple magnetic phases being demonstrated. A phenomenological picture of the evolution of spin reorientation under external magnetic fields is proposed as physical insight into the rich magnetic properties of ${\mathrm{MnPS}}_{3}$. Our findings examine an exciting frontier in fundamental investigations of low-dimensional antiferromagnets and open a path towards the realization of conceptual electronic devices.
