%X This study documents the mammalian diversity in the Tambopata River middle basin, one of the most important information gaps in Peru. Five sites were evaluated in Puno (San Ferm¨ªn 850 m, Curva Alegre 950 m, Challohuma 1200 m, Yanahuaya 1600 m, and Yanacocha 1985 m). The trapping effort was 7072 trap-nights and 201 mistnet-nights. 76 species were recorded in the study area, including 16 species under some conservation¡¯s category. Bats and rodents were the most diverse orders (67.5%). The diversity indices of Shannon-Wiener and Simpson for small mammals show a moderate and mild negative correlation with elevation, respectively. Meanwhile the altitude is negatively correlated with the relative abundance (RA) of bats, and positively with the RA of non-volant mammals. The marsupials Marmosa (Micoureus) demerarae, Marmosops bishopi and Marmosops impavidus; the rodent Neacomys musseri, and bats Platyrrhinus albericoi, P. masu, P. nigellus, Eumops auripendulus and Cormura brevirostris are first records for the department of Puno. Akodon baliolus and Oxymycterus juliacae are considered valid species. The species Sturnira lilium and Akodon baliolus were those with the highest RA. Our records, added to published and unpublished data, indicate that the R¨ªo Tambopata watershed is habitat of 141 species of mammals. Finally, we recommend the extension of the southern part of the buffer zone of the PNBS to include the montane forests of Yanacocha, to protect the unique middleelevation fauna of the R¨ªo Tambopata watershed. El presente trabajo documenta la diversidad de mam¨ªferos en la cuenca media del r¨ªo Tambopata, uno de los vac¨ªos de informaci¨®n m¨¢s importantes del Per¨². Se evaluaron cinco localidades en Puno (San Ferm¨ªn 850 m, Curva Alegre 950 m, Challohuma 1200 m, Yanahuaya 1600 m y Yanacocha 1985 m). El esfuerzo de captura fue de 7072 trampas noche y 201 redes noche. Se registraron 76 especies en el ¨¢rea de estudio de los cuales 16 especies estaban bajo alguna categor¨ªa de conservaci¨®n. Los murci¨¦lagos y los roedores fueron los ¨®rdenes m¨¢s diversos (67,5%). Los ¨ªndices de diversidad (H¡¯ y Simpson) de los mam¨ªferos menores muestran una correlaci¨®n negativa y moderada con la altitud. La Abundancia Relativa (AR) de los murci¨¦lagos tuvo una fuerte correlaci¨®n negativa respecto de la altitud, mientras que los mam¨ªferos peque os terrestres una fuerte correlaci¨®n positiva. Los marsupiales Marmosa (Micoureus) demerarae, Marmosops bishopi y Marmosops impavidus; el roedor Neacomys musseri; y los murci¨¦lagos Platyrrhinus albericoi, P. masu, P. nigellus, Eumops auripendulus y
