Amazonas (P120) is a Amazonas-class offshore patrol vessel currently operated by the Brazilian Navy.

She was originally named Port of Spain (CG50) while she was being built for the Trinidad and Tobago Coast Guard.

Then, despite two of the vessels having been completed at the time and awaiting delivery, and with crew training ongoing in the United Kingdom,[3] the Government of the Republic of Trinidad and Tobago (GORTT) cancelled the order in September 2010.

[5] Port of Spain was built by BAE Systems Maritime in Portsmouth and launched on 18 November 2009.

The ship was sold to the Brazilian Navy and renamed Amazonas (P-120).
