Rattan Singh Ajnala (born 16 January 1944) was a member of the 15th Lok Sabha of India and represented the Khadoor Sahib constituency of Punjab.
He represented the Tarn Taran constituency of Punjab in the 14th Lok Sabha and is a former member of the Shiromani Akali Dal (SAD) political party.
But after a couple of days, he left and rejoined the Shiromani Akali Dal (Taksali) again because he said he still felt annoyed with Badal.
However his son Amarpal Singh Ajnala still remained with the Shiromani Akali Dal.
