SOUTH COAST • OREGON COAST CITY GUIDE
Coos Bay, Oregon
Coos Bay is the South Coast’s largest city and regional hub, a working bay community shaped by shipbuilding, timber, fishing, marshland and immediate access to dunes, forests and dramatic ocean headlands.
HISTORY & CHARACTER
A little Coos Bay history
The Coos Bay region is the ancestral homeland of the Coos, Lower Umpqua, Siuslaw and Coquille peoples. The modern city began as Marshfield in the 1850s and grew around coal, timber, shipbuilding, fishing and the protected waters of Oregon’s largest bay.
For decades, small steamers and other boats formed a ‘mosquito fleet’ that moved passengers and freight between communities around the bay. Rail service arrived in 1916, strengthening connections with inland Oregon, while Highway 101 later reshaped regional transportation.
Residents voted to change the city’s name from Marshfield to Coos Bay during World War II, and the change became official in 1945. The old name survives in the historic Marshfield District downtown, tying today’s city directly to its 19th-century roots.
DID YOU KNOW?
Coos Bay used to be Marshfield
The city officially carried the name Marshfield for roughly nine decades. Even after the 1940s name change, the downtown historic district kept the old name — one of the clearest reminders that Coos Bay has changed identities without forgetting its past.

NATURE & WILDLIFE
Wildlife to watch for
The bay and nearby coast support harbor seals, California sea lions, bald eagles, herons, cormorants and large numbers of waterfowl. Gray whales pass Cape Arago and Shore Acres during migration, while Roosevelt elk and black-tailed deer inhabit surrounding forests. Tidepools and offshore rocks support abundant marine life and nesting seabirds.

GOOD TO KNOW
Practical tips for Coos Bay
The bay area is spread out
Coos Bay, North Bend and Charleston function as one connected region. Allow extra time for drives to Shore Acres, Cape Arago and dune access points.
Storm watching from a safe place
Shore Acres can produce spectacular winter surf. Use formal observation areas and never approach cliff edges or wave-washed rocks.
Expect working traffic
Logging trucks, port traffic and fishing operations are part of the local economy. Give larger vehicles room and stay clear of active docks.
