Abstract: The efficient separation of oil and water is crucial for environmental protection and resource management. Due to tunable structures and functionalities, metal–organic frameworks (MOFs) have emerged as promising membrane‐based oil/water separation materials. This review explores the significant influence of wettability on the performance of MOF membranes in this application. We examine three primary categories: hydrophilic/oleophobic, hydrophobic/lipophilic, and switchable wettability MOF membranes, detailing their synthesis, separation mechanisms, and performance characteristics. The analysis reveals that while all three types can achieve high separation efficiencies, hydrophilic/oleophobic membranes often exhibit superior flux. A key challenge is membrane fouling, and strategies for regeneration and self‐cleaning, particularly those leveraging switchable wettability, are discussed. This review highlights wettability's importance in dictating MOF membranes' performance for oil/water separation. It identifies key areas for future research to enhance membrane stability, scalability, and effectiveness in addressing real‐world water purification challenges. [ABSTRACT FROM AUTHOR]
