Daniel Zialcita Romualdez (September 11, 1907 – March 22, 1965) was a Filipino politician who served as Speaker of the House of Representatives of the Philippines from 1957 to 1962.

His paternal grandfather Daniel was owner of the Malacañang Gardens, the huge expanse of land dedicated to entertaining guests of Philippine presidents.

Another uncle, Dean Vicente Orestes Romuáldez y Lopez, was the father of Imelda Marcos and grandfather of the current Tacloban Mayor Alfred Romualdez.

Romualdez' great-grandfather was involved in the Sumuroy Revolt but narrowly escaped Spanish execution when he was allowed by David Dulay to visit his ailing mother.

Romualdezes were original members of the Nacionalista Party and his old home on Dapitan Street Extension, Quezon City, was its regular meeting place.
