Pelargonium panduriforme (Oak-leaved geranium) is a non-native California shrub in the Geraniaceae family, recognized by deeply divided oak-like leaves and large bilateral flowers.

Oak-leaved geranium is a naturalized shrub found in the central and southern California coastal regions in disturbed sites at elevations below 300 meters. Flowering essentially year-round, this plant produces pink flowers 30 to 40 millimeters wide with delicate bilateral symmetry. Growing over one meter tall with multiple branching stems, it develops a complex structure with extensive lateral growth. Its leaves are distinctive, typically 12 centimeters long and pinnately divided nearly to the midrib, with 3 to 7 unequal serrated divisions that are soft and occasionally slightly sticky. The plant bears flower clusters containing 3 to 10 individual blooms, creating an open and somewhat loose inflorescence.
