Gertrude Boyle (née Lamfrom; March 6, 1924 – November 3, 2019) was a German-born American businesswoman in the U.S. state of Oregon.

After her family fled Nazi Germany, her father founded the business that became Columbia Sportswear, where in 1970, she became company president.

Starting in the 1980s, she appeared in a series of advertisements for Columbia Sportswear with her son, Timothy Boyle, often humorously testing the quality and durability of their products.

[2] The company struggled and teetered on bankruptcy[5] until, in the 1970s, she and her son Timothy refocused the business on outdoor clothing and casual wear which paralleled a general trend away from formal work attire.

[3] In 1983, Boyle became chairwoman of Columbia's board of directors[1] (a position she ultimately retained for 36 years, until her death in 2019).

[2] Columbia was unique among specialty clothing manufacturers in that it would sell its products to any retail shop or chain.

[10] In 1948, she married Joseph Cornelius "Neal" Boyle, an Irish American from Pennsylvania whom she met in college, at All Saints Church in Portland, Oregon.

[2] In 2013, her son Tim was the CEO of Columbia;[11] Kathy is an artist and real estate saleswoman and Sally is the co-owner of Moonstruck Chocolate, an upscale chocolatier.
