Venus definitely is an inner planet: it never appears far from the Sun

There are two ways of defining the inner and outer planets.

  1. Those planets whose orbits around the sun lie within the earth's own orbit: Mercury and Venus. The sun and moon are either categorized separately as the luminaries or are included as inner planets.
  2. Planets that move relatively quickly around the sun and thus are not "generational" planets in signs; and that relate more closely to personal life experiences.

In contrast, outer planets are defined either as orbiting outside of the earth's orbit, or as spending so much time in a given sign that they define an entire generation.
