Sagadava "Manna" Naidoo (4 December 1948 – 25 May 2022) was a South African politician.
He represented the United Democratic Movement (UDM) in the National Assembly from February to November 2000 and was also a former mayor of Verulam, KwaZulu-Natal.
Instead, he joined the National Assembly on 1 February 2000, filling the casual vacancy in the UDM caucus that arose after Roelf Meyer resigned.
His body was discovered on a sugar cane plantation in Canelands, north of Durban, the following day.
He had been tied up and shot several times in a suspected farm invasion; his Toyota Hilux and several firearms had been stolen from his home.
