However, less is known about how existing Facebook groups support professional networking, shared practice, and informal continuing professional development among Filipino nurses. This study aimed to explore professional networking and shared practices among Filipino nurses in Facebook-based online communities. Methods & Materials: A qualitative netnographic design was used. Filipino nursing-related Facebook groups were searched and screened using data-site criteria adapted from netnographic procedures, including relevance, coverage, activity, interactivity, and accessibility. Nine groups were included. Online observations were supported by Zoom interviews with 10 Filipino registered nurses and reflective field notes. From 11,134 collected posts and comments, 1,045 were selected for detailed analysis using a sequential deductive-inductive qualitative approach guided by community of practice theory and social capital theory. Results: Facebook groups supported advice-seeking, job sharing, resource exchange, peer encouragement, milestone recognition, professional updates, and informal learning. Shared practices differed by group purpose. Domestic-focused groups centered on local employment, licensure, and workplace issues; foreign-associated groups focused on migration and overseas practice; and learning-oriented groups prioritized review materials, webinars, and professional development resources. Conclusion: Facebook-based online nursing communities provided accessible spaces for peer-supported learning, professional connection, and informal continuing professional development. Their practical value depends on responsible use, verification of information, ethical conduct, confidentiality, and appropriate moderation. https://npt.tums.ac.ir/index.php/npt/article/view/5256
