The Ida Tarbell House is a historic house at 320 Valley Road in Easton, Connecticut.
 A simple farmhouse dubbed "Twin Oaks", it was the home of muckraking journalist Ida Tarbell (1857-1944) from 1906 until her death.
 She purchased the property with proceeds from her two-volume book on the Standard Oil Company.
 Most of her writing after 1906 was done in the study on the first floor.
 The house was declared a National Historic Landmark in 1993 for its association with Tarbell's professional life.
Ida Minerva Tarbell (November 5, 1857 – January 6, 1944) was an American teacher, author and journalist.

 She is best known for her 1904 book, "The History of the Standard Oil Company", which was listed as No. 5 in a 1999 list by New York University of the top 100 works of 20th-century American journalism.
 It was first serialized in "McClure's Magazine" from 1902 to 1904.
 She depicted John D. Rockefeller as crabbed, miserly, money-grabbing, and viciously effective at monopolizing the oil trade.
 She wrote many other notable magazine series and biographies, including several works on President Abraham Lincoln, revealing his early life.
