As of July 2012 there are twenty-three member museums plus four heritage tourism partners in the Renfrew County Museums Network (RCMN).  The network was set up in 2002 to help promote the many, mostly seasonal, museums in this largest provincial county located in eastern Ontario northwest of Ottawa.

Most members have their own web sites, which are accessible through the RCMN web site at www.renfrewcountymuseums.org.
