This study aimed to examine the relationship between the lifelong learning trends of preservice teachers and the online information searching strategies used by them. Accordingly, this is a quantitative study using the correlational research design. The study group was composed of 317 preservice teachers studied at Sakarya University. The Lifelong Learning Trends Scale and the Online Information Searching Strategy Inventory were utilized. It was concluded in the study that there was a statistically significant relationship among Lifelong Learning Trends Scale and all factors of the Online Information Searching Strategy Inventory. The stepwise regression model which was created to determine to what extend all the online information searching strategies predict lifelong learning trends was statistically significant. It was observed that preservice teachers' lifelong learning trends were statistically and significantly predicted by problem-solving strategies in the first place which were followed by disorientation strategies and purposeful thinking strategies, respectively.
