Indonesia is currently facing the problem of stunting. Stunting is a chronic nutritional problem due to a lack of nutritional intake for a long time, causing impaired growth and development in children. Tuban Regency, East Java, is one of the districts with relatively high stunting cases. The highest stunting case in the Tuban district occurred in Semanding District. The high number of stunting cases is caused by many young women who experience anemia and the lack of public attention to child nutrition. This indicates a shared understanding of stunting. Therefore, it is necessary to study the level of health literacy on stunting to be used as a reference for the government to improve health literacy to overcome stunting. This study aims to measure the level of health literacy on stunting in Semanding District, Tuban Regency, East Java. The method used is descriptive and survey with a quantitative approach. While the analysis technique used is descriptive statistical analysis. The results of this study are the understanding of health, disease prevention, the ability to assess health promotion information, and the application of information from health promotion classified as very good. Meanwhile, the ability to access health information and disease prevention, the ability to assess disease prevention efforts, the implementation of disease prevention, and the ability to access health promotion are also classified as good. However, two factors have the lowest average: mastery of health issues and the ability to assess information from the mass media, both print and online. In conclusion, the level of public health literacy in Semanding District on stunting is already high, but there are still factors that need more attention to improve.
