Count Bertalan Széchényi de Sárvár-Felsővidék (24 October 1866 – 3 June 1943) was a Hungarian politician, who served as Speaker of the House of Magnates from 1 May 1935 until his death.

After that he traveled around the world, including Germany, Italy, Switzerland, Egypt, and some parts of Africa and Anatolia.

He was appointed heritage member of the House of Magnates on 1 June 1894 by King Francis Joseph.

The House of Magnates was dissolved after the Aster Revolution, on 16 November 1918, so he lost his parliamentary seat.

He was appointed Speaker of the Upper House in 1935, following Baron Gyula Wlassics in that position.
