From the perspective of feminist geography, this paper interprets the relationship between gender and spatial distinction in Doris Lessing's The Grass Is Singing: due to the gender division of labor and gender stereotypes in the patriarchal society, the protagonist Mary is restricted to the feminized private space; the private space also reflects and reinforces Mary's position as the weak and hinders her potential for selfreliance. The relationship between gender and spatial distinction is that of interaction and interintensification rather than the apparent “natural” one.
