Kitaca (Japanese: キタカ, romanized: Kitaka) is a rechargeable contactless smart card ticketing system for public transport in Sapporo, Japan.

Like other electronic fare collection systems in Japan, the card uses RFID technology developed by Sony corporation known as FeliCa.

The card's mascot is an ezo momonga (Pteromys volans orii), a type of flying squirrel found in Hokkaidō, and was designed by Sora, an illustrator who lives in Sapporo.

A plan to introduce an Osaifu-Keitai compliant mobile payment system was cancelled due to the cost.
