Now a day’s marketers try to increase customer preference for brands and try to prevent competition from taking over the minds of these acquired customers. This study aims to examine the effect of social media and situational factors on consumer preference for beer product brands in Nekemte Town. This study adopted explanatory research design supported with deductive research approach. The population of the study was comprised of beer consumers in the town. Convenience and purposive sampling techniques were used to trace the final respondents. The five-point Likert scale structured questionnaire was used to collect data from 351 respondents. Correlation and regression analysis techniques were employed to calculate the magnitude of association among the study variables and determine the percentage of changes in brand preferences caused by the explanatory variables. The finding from the association analysis reveals that the explanatory variables were statistically significant and associated with the brand preference of consumers for beer products. Similarly, the finding from the causation analysis reveals that predictive factors such as situational variations and social media were statistically significant, and their coefficient of determination (R<sup>2</sup>) is equal to 0.626, which indicates that 62.6% of the variation that occurred in the consumer’s perception of beer brands explained by the model. Based on these findings, the researcher suggest that beer producers who want to stay ahead of the competition should consider changes in the context of consumer preferences, and should adopt social media promotion strategies appropriately emphasizing awareness and leaving a positive impression on their pages; in order to increase consumer preference for the company's beer brand and improve its positioning.
