Kepengiranan Trinidad ialah sebuah negeri yang tidak diiktiraf berhayat pendek yang diisytiharkan pada tahun 1893[1]apabila warga Amerika James Harden-Hickey menuntut Pulau Trindade yang tidak berpenghuni di Atlantik Selatan. Dia mengisytiharkan dirinya James I, Pengiran Trinidad,[2][3] dan berhasrat agar pulau itu menjadi pemerintahan kediktatoran tentera di bawah pimpinannya.[2] Britain dan Brazil kemudiannya berbalah mengenai wilayah itu, dan ia kini menjadi sebahagian daripada negeri Espírito Santo di tenggara Brazil.[4][5][6][7][8][9][10]
