Bryn Mawr (/ˌbrɪnˈmɑːr/, from Welsh for 'big hill') is a census-designated place (CDP) located in Pennsylvania, United States. It is located just west of Philadelphia along Lancaster Avenue, also known as U.S. Route 30. As of 2020^[update], the CDP is defined to include sections of Lower Merion Township, Montgomery County, as well as portions of Haverford Township and Radnor Township in Delaware County.

Bryn Mawr is located toward the center of what is known as the Main Line, a group of affluent Philadelphia suburban villages stretching from the city limits to Malvern. They became home to sprawling country estates belonging to Philadelphia's wealthiest families during the Gilded Age, and over the decades became a bastion of old money. As of the 2020 census, it had a population of 5,879. Bryn Mawr is home to Bryn Mawr College, and contains a sizable amount of student rentals, with roughly half of the community's population aged 18–24.
