Background: Suicidal ideation has long been associated with HIV infected populations worldwide. It has been found that HIV does not only attack the immune system of an individual but also the nervous system leading to psychological dysfunction of an individual. Objective: To establish the prevalence of suicidal ideation among people living with HIV and AIDS. Method: A cross sectional quantitative design was adopted. Systematic random sampling method was used to select the sample. The total sample comprised of 280 participants. A social demographic questionnaire and Suicidal Risk Screening Scale (SRSS) were used to collect data. Results: The study findings from the SRSS test revealed that (n=193, 69%) of the participants had lower suicide risk while (n=87, 31%) fell into the higher suicide risk category. The study therefore showed that the prevalence of suicidal ideation was 31%. Conclusion: Suicidal ideation was prevalent among people living with HIV and Aids.
