Abstract Hawking radiation from black hole horizon can be viewed as a quantum tunnelling process, and recent research shows fermions via tunnelling from black holes can correctly recover Hawking temperature. In this letter, considering the tunnelling particles with spin 1/2 (namely, Dirac particles), we further improve Kerner and Mann's fermions tunnelling method to study Hawking radiation via tunnelling from rotating black holes in de Sitter spaces, specifically including that from Kerr–de Sitter black hole and Kerr–Newman–de Sitter black hole. As a result, Hawking temperatures at the event horizon (EH) and the cosmological horizon (CH) are well described via Dirac particles' tunnelling.
