Timothy Douglas Harford (born September 1973) is an English economic journalist who lives in Oxford.

Harford is the author of four economics books and writes his long-running Financial Times column, "The Undercover Economist", syndicated in Slate magazine, which explores the economic ideas behind everyday experiences. His column in the Financial Times, "Since You Asked", ran between 2011 and 2014 and offered a sceptical look at the news of the week.

In October 2007 Harford assumed the presenter role at the BBC Radio 4 broadcast segment More or Less. The series segments are also available as podcasts. Subsequently Harford launched his own podcast on the podcast production network Pushkin Industries, called Cautionary Tales.
