Planned Parenthood Mar Monte (PPMM) is the largest Planned Parenthood affiliate in the U.S., providing medical and education services to more than 220,000 people annually at over 30 health center locations in mid-California and northern Nevada.

PPMM was formed by a series of mergers of Planned Parenthood affiliates and independent health centers during the 1990s. The affiliate's name was chosen to reflect a service area that stretches from the sea (mar) through the mountains (monte).

Health services include birth control, emergency contraception, pregnancy testing, prenatal care, abortion, adult general care, breast and cervical cancer screening, pediatrics and well-baby care as well as testing and treatment for sexually transmitted diseases, HIV testing, and sterilization.
