  This white paper presents the current status of the R&D for Analysis
Facilities (AFs) and attempts to summarize the views on the future direction of
these facilities. These views have been collected through the High Energy
Physics (HEP) Software Foundation's (HSF) Analysis Facilities forum,
established in March 2022, the Analysis Ecosystems II workshop, that took place
in May 2022, and the WLCG/HSF pre-CHEP workshop, that took place in May 2023.
The paper attempts to cover all the aspects of an analysis facility.
