Merrimac is a suburb on the Gold Coast in Queensland, Australia. At the 2011 Census, Merrimac had a population of 6,321. The community takes its name from two possible sources: the Merrimack River in the New England region of the United States, or the USS Merrimac, a Union navy frigate itself named for the river.
Merrimac is located on the floodplains in the central region of the city. Merrimac is the site of new housing and building developments as of March 2006.
The South East Queensland Infrastructure Plan and Program allows for an infill station to be constructed in Merrimac on the Gold Coast railway line, between the Nerang and Robina railway stations.
