NOW 2022 is the 11th workshop of a series started in 1998 in Amsterdam. In the years 2000-2016, this international workshop took place in Otranto (Lecce, Italy). This edition, as in 2018, will take place in Rosa Marina (Ostuni, Brindisi, Italy). NOW is locally organized by the INFN sections and Depts. of Physics of Bari and Lecce, ​and is one of the major conference series recognized by INSPIRES in the field of neutrino physics. The aim of the workshop is: to discuss Neutrino Oscillation Physics, in particular current experimental data and their theoretical interpretation; to outline future investigations of neutrino masses and mixings; and to explore the links with various research fields in Astroparticle Physics and Cosmology. The structure of the Workshop includes five sessions, with plenary and parallel talks on several topics of current interest. 
The sessions for the NOW 2022 edition are: 
• Session I - Oscillation parameters: present
• Session II - Oscillation parameters: future
• Session III - Multimessenger astrophysics
• Session IV - Neutrino masses, states and interactions
• Session V - Particle physics in the Cosmos

The workshop will be held, from 4 to 11 September 2022, at the Ostuni Rosa Marina Resort (Rosa Marina, Ostuni, Italy). ​The venue is at walking distance from the seaside. Because of limitations in accommodation and to fulfill the workshop requirements, participation is by invitation only, and is limited to about 140 participants. The Proceedings of NOW 2000, 2004, 2006, 2008, 2010, 2012 and 2014 have been published on Nucl Phys. B (Proc. Suppl.) Vol. 100, 145, 168, 188, 217, 237-238, and 265-266, respectively. The proceedings of NOW 2016 and NOW 2018 have been published on PoS ( and respectively).
