Hanagavadi Siddhaveerappa (12 June 1906 – 28 April 1981) was an Indian barrister and politician from the State of Karnataka.

During this time, in the early 1940s, he also worked toward welfare of the local farmers, helping them with procuring farming implements among others.

In 1952, the first legislative assembly election of the newly formed Mysore State of independent India, he successfully contested the Harihar constituency with an Indian National Congress (INC) ticket.

The JP secured the second most seats in the Assembly and was the opposition party to the INC government headed by Veerendra Patil.

Siddhaveerappa was confident on being conferred the post considering Prime Minister Indira Gandhi had campaigned for him in Davanagere prior to the election, and had called him the next major leader of the State.

However, the post went to Urs, and Siddhaveerappa was appointed the Minister of Health and Family Welfare in his cabinet.
