阿塔瓦波河畔圣费尔南多是委内瑞拉的城镇，由亚马逊州负责管辖，位于该国西南部，始建于1758年，海拔高度65米，2007年人口约15,000。

San Fernando de Atabapo was the capital city of Venezuela's Amazonas state until the early 1900s. The population in 1997 was approximately 5,000.

In the early twentieth century it was ruled for a long time by Tomas Funes, a powerful caudillo who controlled the local rubber industry (derived from indigenous rubber plants) by enslaving the local native populations. His power eventually became great enough to threaten the Venezuelan authorities and he was ultimately executed in the town square in the early 1930s. The town displays a photograph of a United States military aircraft that was shot down and crashed into the Orinoco River around this time. A Venezuelan National Guard unit is stationed here.
