Kitaca (キタカ, Kitaka) is a rechargeable contactless smart card ticketing system for public transport in Sapporo, Japan. Hokkaidō Railway Company (JR Hokkaidō) introduced the system from October 25 2008. Its name means "the card of north (北, kita)", while 北 is also the first character of Hokkaidō (北海道). Like other electronic fare collection systems in Japan, the card uses RFID technology developed by Sony corporation known as FeliCa. The card has an official mascot of Ezo momonga (Pteromys volans orii), a kind of flying squirrel found in Hokkaidō. The mascot is designed by Sora, an illustrator who lives in Sapporo. 
55 stations in Sapporo area, including unmanned stations, accept Kitaca.
- Hakodate Main Line: From Otaru to Iwamizawa
- Chitose Line: From Sapporo to Shin-Chitose-Kūkō (New Chitose Airport) and to Tomakomai
- Sasshō Line (Gakuentoshi Line): From Sapporo to Hokkaidō-Iryōdaigaku
Types of cards

Credit card function is also considered. North Pacific Bank, the largest local bank of Hokkaidō, considers to include Kitaca's functions to its credit card Clover. A plan to introduce an Osaifu-Keitai compliant mobile payment system was cancelled due to the cost. 
Kitaca can be used anywhere that JR East's Suica from spring 2009, including its electronic money function.  Since late 2012, the card can also be used in lieu of a SAPICA, a smart card system introduced by Sapporo City Transportation Bureau from January 2009..
