Arenas is a barrio in the municipality of Utuado, Puerto Rico.

[3][4][5] Arenas was in Spain's gazetteers[6] until Puerto Rico was ceded by Spain in the aftermath of the Spanish–American War under the terms of the Treaty of Paris of 1898 and became an unincorporated territory of the United States.

In 1899, the United States Department of War conducted a census of Puerto Rico finding that the population of Arenas barrio was 1,577.

Funding was available in February 2021 to reconstruct a bridge in Arenas barrio which was destroyed by Hurricane Maria in 2017.
