Background: Bipolar disorder is a serious mental illness associated with an increased risk of suicidal thoughts and behaviour. Resilience, or the ability to adapt and manage stress and adversity, maybe a major factor in lowering this risk and improving outcomes for people with bipolar disorder. Aim: The current study aimed to assess the relationship between psychological resilience and suicidal thoughts in bipolar disorder patients. Design: A descriptive correlational design was adopted in the present study. setting: The research was carried out in the "Psychiatric Medicine and Addiction Prevention Hospital—Cairo University Hospitals" inpatient and outpatient departments. Sample: A purposive sample of 50 male and female bipolar illness patients selected for this investigation. Tools: A structured interview sheet collecting socio-demographic and medical information, the Connor-Davidson Resilience Scale, and the Morey Suicidal Ideation Scale were used to collect data. Results: The results showed that (46.60%) of the bipolar patients tested had a low degree of resilience, (42.20%) had a moderate level of resilience, and only a small fraction (11.2%) had a high level of resilience. Suicidal thoughts were present in 66.60% and 33.40% of studied bipolar patients, respectively. In  bipolar disorder patients, there is no statistically significant relationship between psychological resilience and suicidal thoughts. In order to build resilience and reduce the risk of suicide thoughts and behaviours in bipolar patients, a complete approach that treats both the medical and emotional elements of the condition is required. Recommendation: A patient education programme is necessary: Nurses can educate patients on the value of resilience and self-care in the management of bipolar disease, as well as providing information on coping techniques and self-care practises that patients can use to improve their well-being
