Fermionic continuous spin field propagating in (A)dS space-time is studied.
Gauge invariant Lagrangian formulation for such fermionic field is developed.
Lagrangian of the fermionic continuous spin field is constructed in terms of
triple gamma-traceless tensor-spinor Dirac fields, while gauge symmetries are
realized by using gamma-traceless gauge transformation parameters. It is
demonstrated that partition function of fermionic continuous spin field is
equal to one. Modified de Donder gauge condition that considerably simplifies
analysis of equations of motion is found. Decoupling limits leading to
arbitrary spin massless, partial-massless, and massive fermionic fields are
