The National Museum (NM) Western Visayas Regional Museum, simply known as the National Museum Western Visayas, is a museum in Iloilo City, Philippines.

The museum is housed in the old Iloilo Provincial Jail building, also known as Iloilo Rehabilitation Center, which was built in 1911 and served as the provincial jail of the province until 2006. It is located within the Iloilo Provincial Capitol Complex in Iloilo City Proper.

The National Museum Western Visayas is housed in the Iloilo Provincial Jail which was built in 1911 and used until its abandonment in the 2000s, after a replacement facility was built in 2006. Its satellite office would be at the Old Jaro Municipal Hall which was given to the National Museum of the Philippines (NMP) in 2014 along with the jail building.

The old prison building was converted into a museum by Lim Construction and Trading, a process which began in 2016. A dome structure was added. In February 2017, the NMP Western Visayas satellite office was established after the renovated Old Jaro Municipal Hall was inaugurated.

In April 11, 2018, a turnover ceremony of the renovated ex-prison building to the NMP was held and the museum was inaugurated as the National Museum Western Visayas.

The museum has five galleries on its lower floor and an open gallery on its second floor. It houses artifacts from different parts of the Western Visayas region.
