This systematic review analyzes the factors that influence home advantage in basketball across various competitions in the United States and Europe. Through an investigation of English- and Spanish-language articles published in EBSCO, Scopus, Consensus, and Web of Science between 2010 and 2024 related to home advantage in basketball, 1682 articles were initially identified. After applying specific filters to ensure that only articles concerning National Basketball Association (NBA), Women's National Basketball Association (WNBA), Euroleague, Spanish basketball, and European basketball were considered, 39 articles met the final requirements for in-depth analysis. The studies analyzed in this review suggested that player performance, player position, and sleep influenced home advantage in competitions in Europe and the United States. Fan behavior had a bigger impact in European competitions, where teams from capital cities have a lower home advantage. In the United States, where teams must travel long distances to play, several studies indicated that teams traveling eastwards tend to perform more strongly than teams traveling westwards. Also of note is that, in many cases, COVID-19 pandemic restrictions reduced home advantage. This review identifies factors contributing to home advantage in basketball, compares competitions in different regions, and proposes ideas for future research such as a greater focus on women's competitions, the impact of television, and the introduction of new performance indicators.
