All over the world, the invincibility of women in politics act as a limitation to the promotion of gender equality and the accomplishment of the sustainable development goals. This paper interrogates the political representation of women in Nigeria's fourth republic. It is driven by the desire to unravel the challenges faced by Nigerian women in their quest for equitable political space and its inference for sustainable development in Nigeria. The findings of the study reveal that there has been significant improvement in the lives of women in Nigeria since the return of democratic governance in 1999. It also indicates that the low representation of women in politics is largely as a result of certain socio-political, economic and cultural hindrances. The paper concludes by stating that the sustainable development goals can only be achieved with gender equality. It recommends that the Nigerian political space should be made accessible to women.
