This article presents critical positive communication pedagogy (CPCP), which synthesizes the fields of critical pedagogy and positive communication pedagogy to promote positive communication practices that develop a social justice sensibility among students. We argue that CPCP contributes to the creation of learner-centered classrooms that promote interpersonal connection, foster feelings of inclusion and belonging, and aid students in achieving sustainable happiness. We provide examples of CPCP in business and professional communication classrooms to promote diversity and inclusion, specifically related to issues of gender and sexuality, race, disability, and class.
