This study mainly aims to reveal the bibliometric profile of research on teacher emotions. To this end, the study sought answers to seven research questions, including the most frequently used keywords and their relation networks, the frequency distribution of articles by country and the collaboration network between countries, the frequency distribution by years and the number of citations, the most prolific scholars, the most cited articles, the frequency distribution of articles by WoS categories, and the most prolific universities. The study employed the bibliometric method. The data were limited to the Web of Science and retrieved only from this database. The first search yielded a total of 598 publications. However, those who did not satisfy the criteria were excluded, and the analysis was conducted on the remaining 521 publications. The findings of the study can be summarized as follows. 255 keywords were used at least twice in the articles (excluding search terms). The top five keywords were "emotion regulation, teacher education, teaching, teacher identity, and emotional labour." The researchers who published on teacher emotions were from 54 different countries, and the five countries with the most publications were the United States, China, Germany, Australia, and England.The most publications were in 2019. The top ten most prolific scholars published 70 articles, and the most cited articles were published in 2011. As for categories, two-thirds of the articles were in "education educational research". The most prolific institution was the University of Munich. The study also provided bibliometric maps, figures, tables, and graphs to illustrate the findings. It can be concluded that teacher emotions are associated with various disciplines. Although there is increasing research on teacher emotions, which has been ignored for a long time, teacher emotions as a research field is in its infancy. As the interest in teacher emotions increases, knowledge will accumulate, and the research capacity will be strengthened.
