Mount Sylvania is an extinct volcano of the Boring Lava Field, the volcanic system on the outskirts of Portland, Oregon. The mountain lies partly within Portland, Lake Oswego and Tigard, and its western slopes hold the Sylvania campus of Portland Community College. The Urdu Wikipedia entry gives its elevation as 298.1 metres above sea level.

The name Mount Sylvania derives from Silvanus, the Roman god of forests. The summit area is known as Nansen Summit Park, named after Norwegian polar explorer and Nobel Peace Prize laureate Fridtjof Nansen. The peak lies partly within Portland, Lake Oswego and Tigard, and the Sylvania campus of Portland Community College occupies its western slopes.

Mount Sylvania lies on the borders of Portland, Lake Oswego and Tigard, so access roads approach the summit from more than one city. Portland Community College's Sylvania campus occupies the western slopes, and its roads and parking areas serve as the main way up. The summit sits at about 298 metres above sea level.

Mount Sylvania lies partly within three cities: Portland, Lake Oswego and Tigard. Its summit, about 298 metres above sea level, is the highest point in the Boring Lava Field within Portland's city limits, so the peak straddles municipal boundaries rather than sitting in one place.
