Erlotinib, sold under the brand name Tarceva among others, is a medication used to treat non-small cell lung cancer (NSCLC) and pancreatic cancer. Specifically it is used for NSCLC with mutations in the epidermal growth factor receptor (EGFR) — either an exon 19 deletion (del19) or exon 21 (L858R) substitution mutation — which has spread to other parts of the body. It is taken by mouth.

Common side effects include rash, diarrhea, muscle pain, joint pain, and cough. Serious side effects may include lung problems, kidney problems, liver failure, gastrointestinal perforation, stroke, and corneal ulceration. Use in pregnancy may harm the baby. It is a receptor tyrosine kinase inhibitor, which acts on the epidermal growth factor receptor (EGFR).

Erlotinib was approved for medical use in the United States in 2004. It is on the World Health Organization's List of Essential Medicines. In the United States,, it costs about US$8,832 per month. In the United Kingdom this amount costs the NHS about £1,632 per month.
