Transgenic plants are plants that have been genetically engineered, a breeding approach that uses recombinant DNA techniques to create plants with new characteristics. They are identified as a class of genetically modified organism (GMO).

Examples of transgenic plants include Bt corn (containing genes from a bacterium, Bacillus thuringiensis) and tobacco (containing the Ti plasmid from Agrobacterium tumaficiens).
