The American Institute of Chemical Engineers (AIChE) is a professional organization for chemical engineers. AIChE was established in 1908 to distinguish chemical engineers as professionals independent of chemists and mechanical engineers.

By 2024, AIChE had over 60,000 members from over 110 countries (sources vary). There are over 350 active student chapters at universities worldwide. Student chapters aim to provide networking opportunities in academia and industry as well as increase student involvement locally and nationally.
