LPNMR 2026 is the eighteenth in the series of international meetings on logic programming and non-monotonic reasoning. LPNMR is a forum for exchanging ideas on declarative logic programming, non-monotonic reasoning, and knowledge representation. The aim of the conference is to facilitate interactions between researchers and practitioners interested in the design and implementation of logic-based programming languages and database systems, and those working in knowledge representation and nonmonotonic reasoning. LPNMR strives to encompass theoretical and experimental studies that have led or will lead to advances in declarative programming and knowledge representation, as well as their use in practical applications.

The previous editions of the LPNMR conference series took place in Dallas (2024), Genova (2022), Philadelphia (2019), Espoo (2017), Lexington (2015), A Coruña (2013), Vancouver (2011), Potsdam (2009), Tempe (2007), Diamante (2005), Fort Lauderdale (2004), Vienna (2001), El Paso (1999), Dagstuhl (1997), Lexington (1995), Lisbon (1993), and Washington (1991).
