The study aimed to reveal if there is a relationship between teachers' and preservice teachers' sense of humour and death attitude. The researchers used correlational research design which is one of the quantitative research designs. Data were collected by using two scales that are "Multidimensional Sense of Humour Scale" and the "Attitude towards Death Scale." As a result of the study, there was a meaningful relationship between sense of humour and attitude toward death for both teachers and preservice teachers. Besides, even if there is no difference between teachers and preservice teachers on sense of humour, there is difference one of the subfactors on death attitude. In the period of COVID-19 pandemic in which people highly face with death anxiety, the results can help to understand the importance of humour. Qualitative studies that could provide a deep understanding of the reasons behind these relationships can be conducted in the future.
