Where is the oil filter on a 2004 Toyota Rav4?

It is located underneath the rear seats. But, underneath the car toward the front passengenger side of the engine. If you look under the front bumper on the passenger side you will see the filter in the corner just under the plastic covering. It will not be visible unless you slide yourself under the car. It is also not visible from looking at the engine from top view. Slide under front passenger side.
