  We propose a covariant holographic conjecture for the entanglement negativity
of mixed states in bipartite systems described by $d$-dimensional conformal
field theories dual to bulk non static $AdS_{d+1}$ configurations. Application
of our conjecture to $(1+1)$-dimensional conformal field theories dual to bulk
rotating BTZ black holes exactly reproduces the corresponding entanglement
negativity in the large central charge limit and characterizes the distillable
entanglement. We further demonstrate that our conjecture applied to the case of
bulk extremal rotating BTZ black holes also characterizes the entanglement
negativity for the chiral half of the corresponding zero temperature
$(1+1)$-dimensional holographic conformal field theories.
