  We study quantum tunneling of charged and uncharged scalar particles from the
event horizon of Schwarzschild-de Sitter and Reissner-Nordstr\"{o}m-de Sitter
black holes pierced by an infinitely long spinning cosmic string and a global
monopole. In order to find the Hawking temperature and the tunneling
probability we solve the Klein-Gordon equation by using the Hamilton-Jacobi
method and WKB approximation. We show that Hawking temperature is independent
of the presence of topological defects in both cases.
