WikiZagłębie.org is a community-built online encyclopedia dedicated to the history, culture, places, and people of the Zagłębie Dąbrowskie region in Poland. Created in 2011 as part of the “Getting to Know Zagłębie Dąbrowskie” project, the site is developed by volunteer members of the Forum dla Zagłębia Dąbrowskiego association and other regional enthusiasts. Its aims are to strengthen awareness of local identity, organize knowledge about the region, and connect people and groups interested in its heritage.

The encyclopedia contains nearly 12,000 entries, covering subjects such as regional history, towns, industrial sites, biographies, traditions, museums, religious communities, cemeteries, public transport, monuments, and sport. Visitors can browse topic catalogs, view photographs, explore daily historical anniversaries, and discover recently added pages. WikiZagłębie also invites readers to contribute by editing articles and sharing photographs; it offers help with scanning older prints and negatives. Supported by regional cultural institutions and archives, the site provides an accessible, collaborative resource for learning about Zagłębie Dąbrowskie.
