The Siqueira Campos Square (Portuguese: Praça Siqueira Campos) or Clock Square (Praça do Relógio) is a public space located at the Ver-o-Peso Dock, in the Cidade Velha neighborhood, in the Brazilian city of Belém, capital of Pará.

It measures 12 meters high, is made of iron and features four lamps in a central clock.

Due to the 1930 Revolution, Eurico Vale and Antonio Faciola were deposed and were unable to inaugurate the work.

Major Joaquim de Magalhães Cardoso Barata, Governor of Pará, and Father Leandro Pinheiro, Belém's Intendant, were present at the event.

The complex covers an area of 35,000 square meters and includes a series of historic buildings such as the Boulevard Castilhos França, the Meat Market, the Ver-o-Peso Market, the Ver-o-Peso Dock, the Açaí Fair, the Ladeira do Castelo and the Solar da Beira.
