  Previous works on black hole shadows have been primarily focused on studying
shadows in asymptotically flat and anti-de Sitter space times. In the present
work, we find general expressions for asymptotically de Sitter black hole
shadow as seen by static and comoving observers, for any spherically symmetric
black hole solution, in any space time dimension in generic theories of
gravity. As test cases, we use the derived general expressions to study the
shadow of three different black hole solutions: the four dimensional
Reissner-Nordstr\"{o}m de Sitter black hole, the recently proposed four
dimensional Gauss Bonnet de Sitter black hole and the five dimensional Gauss
Bonnet de Sitter black hole.
