Second home tourism has emerged as a significant area of research on tourism-related mobility and multiple dwelling. The article conducts a review of the academic literature and is divided into two main parts. The first part charts the growth of second home publications in relation to countries of authors, leading journals, and number of publications. The second part discusses major themes in second home research including motivations, location, planning, housing, social and community dimensions, environmental dimensions, and governance. Future research themes are also identified. The article concludes by noting that while the implications of mobility and multiple dwelling for urbanization processes and change to amenity environments, there was a need for greater attention to life course and relational approaches to better understand the temporal and spatial dimensions of second homes.
