Dengue fever (DHF) is an infectious disease that is still a public health problem in Indonesia, including in Gresik District. Environmental factors, especially sanitation, have an important role in the spread of this disease.

This study used a quantitative analytic approach with a cross sectional design. The number of respondents was 106 people selected using random sampling technique. Data collection was done through questionnaires and observation, then analyzed using the chi-square test.

The conclusion of this study is that environmental sanitation has a significant relationship with the incidence of DHF, so it is necessary to improve sanitation as a preventive measure in the community.
