Christmas Bay (Texas)

Christmas Bay is a shallow bay located on the Texas Gulf Coast in Brazoria County, Texas, southwest of West Bay near the Galveston Bay system. It is a minor estuary protected from the Gulf of Mexico by Follet's Island, with tidal exchange through San Luis Pass and Cold Pass. The bay connects to Bastrop Bay on the north and Drum Bay on the southwest. The nearest city is Freeport, approximately 10 miles (16 km) away at the mouth of the Brazos River.

Christmas Bay covers 4,173 acres (1,689 ha) and is recognized for its high water quality, extensive oyster reefs, and fringing salt marsh habitat dominated by Spartina alterniflora and Batis maritima. Much of its shoreline lies within the Brazoria National Wildlife Refuge, contributing to its ecological integrity. The bay is designated as a Texas Coastal Preserve and a State Scientific Area due to its ecological productivity and minimal anthropogenic disturbance.
