Objective: To determine the incidence of extreme violence against women (EVAW) and femicide; and some risk factors in Peru. Methods: Observational research of secondary data (2009-2015) from the Ministry of Women and Vulnerable Populations of Peru. MS Excell® program was used to calculate the gross rate of extreme violence against women and femicide by territory, year, month, bond, scenario, and area. Results: In the period 2009-2015, the rate of extreme violence against women has increased. Tacna (RT=2,673; IC 95 %=2,111-3,384) had the highest rate of femicide´s risk, and Madre de Dios (RT=2,475; IC 95 %= 1,462-4,188) had the highest risk of extreme violence against women. There was greater risk of extreme violence against women in January (RT=1.204, IC95%=1.019-1.422) and femicide´s risk in November (RT=1.463, IC95%=1.173-1.826) and January (RT=1.280, IC95%=1.014-1.616). Extreme violence against women is more likely to end in femicide when the aggressor is unknown (ORc= 11.950; IC 95 %=6.572-23.510), when is an acquaintance (ORc=2,644; IC 95 %=1,736-4,094) or a relative (ORc= 1,614; IC 95 %= 1,078-2,433), in a non-intimate place (ORc=5,522; IC 95 %= 3,611-8,629), in the rural area (ORc= 1,692; IC 95 %= 1,136-2,525), or in the marginal urban area (ORc=1,678; IC 95 %= 1,057-2,673). Conclusions: Extreme violence against women’s incidence has increased. The risk of femicide is higher in November, in the rural and marginal urban areas, in a nonintimate scenario, and when the extreme violence against women is not perpetrated by the partner or ex-partner.
