This study examines the concept of brand personality within the context of its theoretical foundations and implementation strategies, then supports conceptual discussions with concrete brand examples. The first section explores brand personality as the process of attributing human qualities to brands, explaining the concept's psychological, sociological, and communicational aspects. Aaker's (1997) brand personality dimensions explore how brands develop emotional and symbolic value, and Fournier's (1998) brand-consumer relationship model assesses the role of brands in individuals' self-construal. Building on this theoretical background, the second section analyzes the strategic dimensions of personality construction through selected brands from diverse sectors. Using exemplary brands, it explains how brand personality is reinforced through tools such as advertising language, visual identity, storytelling, and experience design. By holistically demonstrating the relationship between theoretical foundations and implementation practices, the study argues that brand personality is not only an element of marketing strategy but also a form of communication that reflects a brand's cultural identity. As a result, today, brand personality stands out as a critical strategic element for brands to gain competitive advantage, establish emotional bonds with consumers and create long-term loyalty.
