Most of the residents are originally from Marmara Island, in the Sea of Marmara, and from Parthenonas, a small village on the mountain, Itamos.

Neos Marmaras was formed in 1925 by Greek refugees from Marmara Island following the Asia Minor catastrophe and exchange of populations with Turkey.

In 1970, the traditional inland hill village of Parthenonas was abandoned and these inhabitants moved down to the coast and also settled in Neos Marmaras boosting its population.

Since the 1980s, Neos Marmaras has become a popular tourist town with numerous cafes, restaurants and bars along the waterfront being very busy in the summer months.

Porto Carras is a big 5-star resort outside Neos Marmaras. It is one of the biggest in northern Greece. There is also a famous wine from Porto Carras called Domaine Porto Carras.

Neos Marmaras has numerous settlements and islands including:

• Paradeisos (Greek: Παράδεισος, pronounced [paˈraðisos]), a small settlement close to Neos Marmaras. It has approximately 40 people and lies just downhill of Marmaras in a low-lying area.
• Agia Kyriaki (Greek: Αγία Κυριακή, pronounced [aˌʝia ciriaˈci]), a very small marina and fishing settlement in a small bay outside Marmaras with some 20 people living there in the summertime.

It rains a lot in the village, specially winter time but the village has seen snow several times. The areas surrounding Neos Marmaras, especially the village of Parthenonas has seen snow almost every winter.
