Košarkarski klub Plama Pur (English: Plama Pur Basketball Club) is a Slovenian basketball club based in Ilirska Bistrica that competes in the Slovenian Second League, the second tier of Slovenian basketball.

The club was founded in 1956 as a basketball section of TVD Partizan Ilirska Bistrica.

In the 1965 season of the Yugoslav First League, Lesonit won only one match, against KK Rabotnički Skopje, ending the season in last place with one win and 21 defeats in 22 matches.

It ceased to operate in the early 1980s, when basketball moved to indoor arenas and Ilirska Bistrica did not have adequate facilities.

[1] It was refounded in 1996 and is now named KK Plama Pur Ilirska Bistrica for sponsorship reasons.
