美国机械工程师学会（American Society of Mechanical Engineers，ASME），是一个以机械工程为主的专业组织，总部位于美国纽约市。它于1880年成立，以因应当时许多蒸汽锅炉，压力容器的故障事故。该组织制定许多众所周知的机械设备法规和标准。ASME出版大量的业务技术刊物，并举行多种会议，数百种专业技术课程、推广教学计划。该组织的目标是在世界各地推动艺术、科学和跨领域学科、机械工程及相关的科学研究。

托马斯·巴洛是2008至2009年度的ASME第127任总裁。

截至2006年，ASME有12万成员。

The American Society of Mechanical Engineers (ASME) is a professional association that, in its own words, "promotes the art, science, and practice of multidisciplinary engineering and allied sciences around the globe" via "continuing education, training and professional development, codes and standards, research, conferences and publications, government relations, and other forms of outreach." ASME is thus an engineering society, a standards organization, a research and development organization, a lobbying organization, a provider of training and education, and a nonprofit organization. Founded as an engineering society focused on mechanical engineering in North America, ASME is today multidisciplinary and global.
