Ithan Creek (also known as Ithan Run[1]) is a tributary of Darby Creek in Delaware County, Pennsylvania, in the United States. It is approximately 4.2 miles (6.8 km) long and flows through Radnor Township and Haverford Township.[2] The creek's watershed has an area of 7.39 square miles (19.1 km2) and is highly developed. It has three named tributaries: Browns Run, Kirks Run, and Meadowbrook Run.
The creek was historically the site of several mills and has been subjected to numerous floods over the years. In 1902, a sewage company began dumping raw sewage into the creek, but this practice was stopped in 1905. The creek is in approved trout waters. It is the site of Ithan Valley Park, a small park with hiking and fishing opportunities and the Radnor Valley Country Club.
