The Independent Liberal Party or Doctrinary (Spanish: Partido Independiente Liberal) was an independent Chilean political party which was formed during Domingo Santa María's presidency by a group of parliament members, known as the doctrinaries, who opposed him.
Its party platform wanted an increase of public liberties, to apply universal suffrage and to establish a real democratic regime.
The ILP could be seen as a tendency in the Liberal Party, it usually shared its candidate lists, but its members used to vote in a different way than the official one.
With the downfall of president Carlos Ibáñez (1931) it rearranged as an autonomous organization.
During the VI Convention of the Liberal Party, in October 1933 the ILP merged into the LP.
