This study investigates the antimicrobial activity of different morphological parts of *Rubus idaeus* L. (raspberry) and its correlation with total phenolic content and antioxidant activity. The research aims to evaluate the potential of raspberry as a natural alternative to synthetic antimicrobials and explore its applications in various industries. The study found that raspberry leaves, inflorescences, and fruits effectively combat three Gram-positive bacteria, while root and seed extracts showed the lowest antibacterial activity. The correlation between antimicrobial activity and phenolic content was moderate for some bacteria but weak or very weak for others. The results suggest that raspberry plant parts can be used to develop natural antimicrobial products, particularly for food preservation, disinfectants, and other applications. The study highlights the potential of raspberry as a valuable resource for creating added-value products and contributes to the growing body of research on natural antimicrobials.This study investigates the antimicrobial activity of different morphological parts of *Rubus idaeus* L.
