This study examines the ecofeminist approach to two iconic works of speculative fiction, The Testaments (2019) by Margaret Atwood and The Dispossessed (1974) by Ursula K. Le Guin, focusing on themes such as authority, colonialism, capitalism, patriarchy, gender inequality, and environmental exploitation. Using an analytical and comparative approach, the study delves into how both novels highlight the interconnectedness of social and ecological oppression. Atwood's The Testaments explores the harmful effects of patriarchal and authoritarian systems on both women and the environment, showing how these oppressive structures destroy women's bodies and deplete natural resources while also underscoring the role of rebellion and resistance within such a system. In contrast, Le Guin's The Dispossessed, which blends dystopian and utopian elements, critiques the consequences of luxury, colonialism, and militarism, linking them to the degradation of both nature and women's health. The study ultimately explores how both novels emphasize the destructive impact of patriarchal, hierarchical, militaristic, colonial, and authoritarian systems on both the environment and women's bodies, underscoring the ecofeminist perspective that these forms of oppression are deeply interwoven
