The Kellogg School of Management at Northwestern University, also known as The Kellogg School or simply Kellogg, is considered one of the world's leading graduate business schools.

Founded in 1908, the school was chartered to educate business leaders with "good moral character." Kellogg pioneered the use of group projects and group evaluations as a means of educating future executives. As a result, the school has been widely credited with popularizing the importance of "teamwork" and "team leadership" within the business world, as other business schools have followed suit in using group projects as educational tools.

Kellogg differentiates itself from other business schools by virtue of: its teaching method, which places equal emphasis on theory and practice; its entrepreneurial culture, which involves students in every facet of the school's decision-making process; its partnerships with other schools in China, India, Hong Kong, Israel, Germany, Canada, and Thailand; and its constantly evolving curriculum, which frequently introduces new courses based on changing market demands.

Kellogg graduates hold leadership positions in for-profit, non-profit, governmental, and academic institutions around the world.
