Pikku Kakkonen (Finnish for "the little number two") is an ongoing Finnish magazine-type children's TV show shown on Yle TV2. The first episode aired on January 11, 1977. It finished with a bedtime story read by the late Lasse Pöysti (1927-2019) and an East German Sandman animation, setting the format for hundreds of later episodes.

Currently the series airs twice a day (mornings and night) on the weekdays and once a day (mornings only) on the weekends.

The Pikku Kakkonen show is based in Tampere, and its signature melodies (The Pikku Kakkonen mail tune and the main title tune) have been made into mobile phone ringing tones. On October 25, 1983, Pikku Kakkonen introduced a new logo that consists of a moon, a flower, a teddybear, a doll, a ghost, a fish, and a bird which together form the number 2; this matches the frequency for Yle's secondary channel. Pikku Kakkonen's current intro animation is illustrated by Camilla Mickwitz who was responsible for designing and animating the stop-motion opening and ending sequences. This logo has become a trademark symbol of Pikku Kakkonen. It will permanently remain in use.

A variety of live-action and animated television series air as part of Pikku Kakkonen, both domestic and imported. The imported series are mainly animated and have all been dubbed and localized into Finnish. The domestic series are mainly live-action.

Pikku Kakkonen is targeted at an audience of preschool and elementary school-aged children. It has a counterpart for older children called Galaxi which also airs on Yle TV2. Galaxi broadcasts live-action and animated television series both from Finland and overseas, all in the Finnish language.
