The COVID‐19 pandemic has significantly affected nursing, as nurses are crucial in providing healthcare services. Understanding the factors influencing nurse retention is essential for maintaining a strong and long‐lasting workforce because nurse retention is becoming increasingly complex. This study aimed to investigate the influence of professional identity and job satisfaction on the intention to remain employed while also evaluating the levels of professional identity, job satisfaction, and intention to stay among paediatric nurses amidst the COVID‐19 pandemic. This correlational and descriptive study included a stratified sample of 257 paediatric nurses and was guided by the STROBE checklist. Data were collected through valid and reliable questionnaires, which included a nurses' professional identity scale, job satisfaction survey, intention to stay scale, and a demographic questionnaire. Data collection was conducted from January to April 2022. The study was approved by the ethical research committee at the Nursing Faculty – Mansoura University, ensuring adherence to the Helsinki Declaration. The paediatric nurses reported elevated professional identity, moderate job satisfaction, and moderate intention to stay employed with mean scores of 80.35 ± 13.22, 113.70 ± 19.58, and 8.40 ± 3.55, respectively. Multiple regression explained 13.0% of the variation in paediatric nurses' intention to remain employed (F = 18.50, p < 0.001). Professional identity positively correlated with the intention to stay (β = 2.69, p = 0.008). Job satisfaction also had a positive relationship with the intention to stay (β = 3.49, p < 0.001). Healthcare managers should focus on professional identity strategies such as supportive work environments, growth opportunities, and valuing paediatric nurses' contributions. Implementing interventions such as fair compensation, support, and rewards can enhance paediatric nurses' retention and quality of patient care.
