Igor Ledochowski (born April 1, 1974) is an Austrian author, hypnotist & Master NLP Trainer. Ledochowski is perhaps most well-known for being the direct descendant of Wlodimir Ledochowski and for his work in the area of hypnosis. He is the author of The Deep Trance Training Manual, Crown Publishers (March 1, 2003).

After receiving his LLB in European Law from the University of Exeter (1996), Ledochowski stayed on to attend Law School and continue his education. In 1998 he was employed and mentored by the law firm Linklaters and became a solicitor.

During his enrolment at University and Law School, Ledochowski developed a keen interest in the field of accelerated learning in order to achieve academic success in his exam finals with the least amount of revision; he passed comfortably and was quickly offered employment. These early successes further spurred his curiosity in uncovering the abilities of the human mind. In 1999, a family member recommended that he might do well to examine the field of Ericksonian Hypnosis, and he quickly found much of his free time dedicated to its study.

Motivated by his experiences, he terminated his position as a lawyer and sought out the stewardship of many of the world's most competent and influential hypnotists in order to further his knowledge in the area. Subsequently, by 2002 he had been trained with leading hypnotists including Stephen Gilligan, Richard Bandler, John LaValle, Stephen Brooks, and John Grinder.

By early 2002, Ledochowski claims he was dissatisfied with the general quality of hypnosis being both taught and administered by professionals. To remedy this, he undertook work in the field of conversational hypnosis and successfully created a system to covertly place subjects into a hypnotic trance. He claims that this work served to augment the existing methods employed by practicing hypnotists whilst drastically increasing the accessibility of hypnosis to the layperson.

In 2003, Ledochowski released Deep Trance Training Manual, Volume 1.
