Port Alsworth is a census-designated place in Lake and Peninsula Borough, Alaska, United States. It is by air southwest of Anchorage. The population was 159 at the 2010 census, up from 104 in 2000. Port Alsworth was founded in 1950 by Babe Alsworth, a missionary and bush pilot, and Mary Alsworth, who was the town's first postmaster. Port Alsworth is located on private land within Lake Clark National Park and Preserve and is the site of the national park's field headquarters. Samaritan's Purse operates a lodge for wounded United States military veterans located within the town for "Operation Heal Our Patriots". There is also a summer camp called "Tanalian Bible Camp" where youth, ages 8–19, from the surrounding villages can attend. From the summer of 2013 to the spring of 2014, the local Tanalian School underwent renovation and a dearly needed expansion. The renovation involved tripling school square footage, all new furniture, and doubling the size of the gym.
