Christopher Thomas Knight (born 7 December 1965), also known as the North Pond Hermit, is a former hermit who lived almost without human contact for 27 years in the woods in the North Pond area of Maine.

Knight lived within about a mile of summer cabins throughout his entire hermitage in a crude camp he built in a well-drained woodland obscured within a cluster of glacial erratic boulders. Because he entered the woods with almost no possessions, his camp was composed entirely of items stolen from nearby cabins and camps. He survived by committing approximately 1,000 burglaries against houses in the area, at a rate of approximately 40 per year.

Apart from the fear and notoriety his many burglaries created in the local area, Knight's unusual life also attracted widespread international media reports upon his capture.

Knight entered the woods in 1986, aged 20, without saying goodbye to anyone. Knight's parents apparently never reported him missing to the police. In an interview, Knight said, "I had good parents", and, "We're not emotionally bleeding all over each other. We're not touchy-feely. Stoicism is expected." The family's next-door neighbor for 14 years hasn't exchanged more than a few words with Knight's mother.

Knight survived the intense Maine winters (with temperatures dipping as low as –25 °F / –32 °C) by waking up during the coldest part of the night and pacing his camp until warm. Knight regularly took cold sponge baths, shaved and cut his hair, in part to avoid suspicion in the event he was spotted by others. He avoided building smoky fires which might reveal the location of his camp, but relied upon a propane camp stove to cook and melt snow for drinking and bathing. Stolen propane cylinders were transported in canoes borrowed from vacant camps. He quietly paddled along the shadowy shoreline in the pre-dawn hours to avoid being silhouetted on open water. Knight concealed thefts by replacing empty propane cylinders for the full ones he removed, and sprinkling pine needles over the canoes he had used when he returned them. Knight stockpiled supplies to remain in his camp from November through March to avoid revealing his location by footprints on snow-covered ground.

At the time of his arrest, Knight claimed that there was only one instance during his 27 years of solitude in which he spoke with another human: at some point in the 1990s, he exchanged the word "Hi," with a hiker whom he encountered on a lightly traveled path.

Biographer Michael Finkel later reported that around February 2013, a fisherman named Tony Bellavance (along with his son and grandson) had discovered Knight in his camp. This was a mere two months before he was apprehended by police. Knight later admitted to having been discovered by the fishermen, but hadn't mentioned it to police at the time of his arrest because the group swore a pact to not tell anyone of their meeting (after the anglers learned that Knight simply wanted to be left alone).

Knight was captured by game warden Sergeant Terry Hughes on April 4, 2013, while burglarizing the Pine Tree Camp in Rome, Maine.

Knight was sentenced to seven months in jail on 28 October 2013, of which he had already served all but a week while awaiting sentencing. In addition to the jail sentence, Knight paid $2,000 in restitution to victims, completed a Co-Occurring Disorders Court Program (designed for people with substance abuse problems and mental health disorders), and completed three years of probation.

Knight has described deep-felt ethical misgivings about the burglaries committed, saying that stealing is wrong. Even the prosecutor said that a longer sentence would have been cruel. Judge Nancy Mills believes it is very unlikely that Knight will re-offend. After release, Knight met with the judge every week, avoided alcohol, and secured a job with his brother.

Knight was largely reluctant to express any inkling of motives or insights gained through his experience, but he did offer that "solitude bestows an increase in something valuable, ...my perception. But...when I applied my increased perception to myself, I lost my identity. There was no audience, no one to perform for...To put it romantically, I was completely free." Finkel compared this observation to similar statements by Ralph Waldo Emerson, Charles de Foucauld, and Thomas Merton.

Many have expressed admiration for Knight's outdoor survival skills, especially in the harsh Maine winters. Some also expressed doubt, believing instead that Knight broke into and took refuge in vacant cabins.

Journalist Michael Finkel met with Knight for nine one-hour sessions while he was in jail. This was the genesis for first an article in GQ magazine in August 2014, and then the book The Stranger In The Woods, published in March, 2017.
