Jenny Rose Guerrero (born October 10, 1984) is a Filipino former swimmer, who specialized in breaststroke events.

Swimming in heat three, she struggled to keep her pace against seven other swimmers, and raced to the last seed in 1:15.14, more than two seconds below her entry standard.

[5][6] Three days later, in the 200 m breaststroke, Guerrero posted a time of 2:38.10 in heat one, but finished farther from the semifinal field with a thirty-first-place effort.

[7][8] At the 2001 Southeast Asian Games in Kuala Lumpur, Malaysia, Guerrero held off a three-way challenge in the pool against host nation's Siow Yi Ting and Singapore's Nicolette Teo, but her relentless effort was worthy enough to take home the silver in the 100 m breaststroke (1:12.91, a fresh Filipino record) and bronze in the 200 m breaststroke (2:36.05).

[10][11] Guerrero is a graduate of University of the Philippines Diliman with a Bachelor of Science degree major in hotel and restaurant management (HRM).
