Abstract: Background: Mpox has become a public health problem due to its rapid evolution and clinical variability. In Latin America, Peru ranks fifth in terms of the number of cases. The main objective of this study is to determine the epidemiological and clinical characteristics of Peruvian patients diagnosed with mpox, providing a detailed view of the situation of this affected population. Methods: A systematic review and meta-analysis of studies on mpox in Peru was carried out using ten databases and search tools (PubMed, Scopus, Web of Science, Embase, ScienceDirect, Google Scholar, Virtual Health Library, Scielo, Dimensions, and Epistemonikos) until August 22, 2024. The MeSH (Medical Subject Headings) terms used in the search were “mpox” and “Peru”, combined with the logical operators AND and OR. Study quality was assessed using the Joanna Briggs Institute (JBI) assessment tool, and pooled estimates were generated using random-effects meta-analysis. Heterogeneity was assessed using the I² statistic. Statistical analysis was performed in R version 4.2.3, and the study was registered in PROSPERO (CRD42024582854). Results: A total of 150 articles were evaluated, of which 9 studies were included: four retrospective observational studies, four case series, and one case report, covering a total of 3960 Peruvian patients with mpox. The quality of the studies was moderate. The combined results show that 97% (95% CI: 96–98%; 3804 participants; 4 studies; I2 = 24%, p = 0.27) of the patients were male, 63% (95% CI: 57–68%; 2366 participants; 4 studies; I2 = 66%, p = 0.03) had HIV (human immunodeficiency virus), and 91% (95% CI: 83–97%; 2019 participants; 4 studies; I2 = 90%, p
