目的 基于国际护士协会（International Concil of Nurses, ICN）颁布的《灾害护理核心能力2.0》（core competencies in disaster nursing version 2.0, CCDN 2.0）框架，探讨新入职护士灾害护理核心能力的潜在类别及其影响因素。方法 2023年7月，采用便利抽样法选取广东省新入职的607名护士为研究对象，使用一般资料调查表和执业护士灾害护理核心能力量表对其进行调查，运用潜在剖面分析、单因素分析和多元Logistic回归分析确定不同剖面及其影响因素。结果 广东省新入职护士的灾害护理核心能力可分为能力尚可组、能力中等-沟通水平低下组 、能力严重不足组3种潜在类别。实习期间灾害应急救护演练经验、ICU实习经历和参加过抗疫志愿服务是潜在类别的影响因素（均P＜0.05）。结论 灾害护理核心能力存在异质性，新入职护士应根据不同类别的影响因素对其进行针对性指导，以提高新入职护士的灾害护理核心能力
