The Kita-Osaka Kyuko 8000 series (北大阪急行電鉄8000形), branded as Polestar, is an electric multiple unit (EMU) train type operated by Kita-Osaka Kyuko Railway on the Kitakyū Namboku Line in north Osaka since 1986, with through service to the Osaka Metro Midōsuji Line.

The 8000 series was introduced in 1986 to replace ageing rolling stock which were mostly derived from Osaka Municipal Subway rolling stock.

It was also the first Kitakyū rolling stock type to feature air conditioning in the passenger interiors and driver cabs.

It was also one of the three recipients of the 27th Laurel Prize of the Japan Railfan Club.
