Lisbon Half Marathon is an annual international half marathon competition which is contested every March in Lisbon, Portugal. It carries IAAF Gold Label Road Race status. The men's course record, set by Zersenay Tadese in 2010, is also the world record for the half marathon distance.Kenyan runners have been very successful in the competition, accounting for over half of the total winners, with Tegla Loroupe taking the honours in the women's race on six separate occasions. The Lisbon Half Marathon is not to be confused with Portugal Half Marathon, another prominent half marathon race which is also held in Lisbon in September.

First held in 1991, the race has consistently delivered fast winning times. However, many of these times have been unratifiable for record purposes due to factors including: the course being too short (1991–93), excessive tailwinds, as well as there being an excessive drop in altitude, which boosted athletes' performances (1996, 1998, 2000-01, 2004, and 2006).

The course was judged as non-permissible for records until 2008, in which year the organisers changed the elite course to allow for records. The new course begins at sea level on the north side of the river Tagus, a change which made the course entirely flat. The course for the mass participation race, which has attracted almost 30,000 runners in previous years, remained unchanged and begins by crossing the Ponte 25 de Abril suspension bridge before linking up with the new elite course.

The current elite course of the half marathon begins in a small town on the north bank of the Tagus, no longer crossing the bridge, and the course is wide and flat from there on. Heading eastwards towards the city centre, the course passes the docks and traces a route alongside much of the city's historical architecture, including the Belém Tower and Jerónimos Monastery.
