The Democratic Nationalist Party or Nationalist Democratic Party (Romanian: Partidul Naționalist-Democrat, PND) was a political party in Romania, established by historian Nicolae Iorga (who was also its longest-serving leader) and jurist A. C. Cuza. Its support base was in the lower reaches of the Romanian middle class, and, especially through Cuza's ideology, it reflected the xenophobia, economic antisemitism, and producerism of that particular environment. The PND was a weak challenge to the mainstream political forces, either conservative or liberal, failing in its bid to become Romania's third-strongest party. By 1916, it was effectively split between Iorga's moderates and Cuza's radicals, suspending its activity for the remainder of World War I.
