The present invention relates to a light guiding device and a lamp for a vehicle including the same, and more specifically to a light guiding device for emitting light of uniform brightness and a lamp for a vehicle including the same. According to an embodiment of the present invention, a light guiding device comprises: an incident unit in which light is incident; and a transmission unit transmitting the light incident to the incident unit to emit the light. The transmission unit includes: an emission unit formed in a direction in which the light is transmitted; and a reflection unit positioned to face the emission unit and having a plurality of optical patterns reflecting the transmitted light to proceed to the emission unit. The reflection unit is divided into a plurality of reflection areas having different separation distances from the incident unit, and an average size of the optical patterns included in each of the plurality of reflection areas among the plurality of optical patterns may be different from each other.
