Allison is a variant spelling of Alison, a medieval French pet form of Alice. Alice in turn comes from the Germanic name Adalheidis, made up of elements meaning noble and type, so Allison is usually taken to mean noble. It is pronounced AL-uh-suhn.
Among the best-known bearers is Allison Janney, the American actress who won Emmys for The West Wing and an Oscar for I, Tonya. Allison Williams, star of HBO's Girls and the film Get Out, is another familiar namesake.
In the U.S., Allison was rare before the 1950s and then climbed for decades. It was given most often in 1994, to 8,150 girls, and reached its highest rank, 30th, in 2009. It has fallen since the mid-2010s and ranked 103rd among girls' names in 2025, with 2,564 babies.
