Supermarket flyers represents a strategy to promote sales and are widely used by consumers. Seasonality interferes in food availability and may be related to marketing. Objective: to evaluate the influence of seasonality on food promotion in supermarket flyers of large five Brazilian supermarket chains, aiming to contribute to the monitoring of food environments.

The ultra-processed foods (UPF) were classified considering the NOVA food classification. The UPF were grouped based on subgroups. The inserts were divided into traditional and seasonal. Seasonality and food promotion were analyzed according to festive dates (“São João”, Father's Day, Christmas, New Year, Carnival, Easter and Mother's Day) and seasons (summer, autumn, winter and spring). Data were presented as absolute and relative frequencies. The chi-square test was used to test differences between outcomes and exposure variables. Results: Warm seasons (summer and spring) showed greater UPA promotion. No increase in the promotion of festivities flyers was found when compared to traditional inserts. Specific festivities holidays showed the increase of promotion of subgroups of UPF. The period of Christmas/New Year and Carnival it was observed layout changes in all networks. Conclusion: There is an influence of seasonality on UPF promotion, especially by certain supermarket chains and specific UPF groups.
