Erika Henningsen

In January 2020, it was announced that Henningsen would be joining the Broadway cast of the new musical, Flying Over Sunset, scheduled to open in the spring of 2020 at the Vivian Beaumont Theater under the direction of James Lapine. However, the production's opening was postponed until the fall of 2020 after theaters were mandated to shut down by Gov. Andrew Cuomo on March 12, 2020 due to the COVID-19 pandemic.

During the COVID-19 pandemic, Henningsen teamed up with She's the First, a non-profit organization committed to providing access to education to all girls, to raise money for their COVID-19 Response Fund by offering access to her exclusive living room concert with any donation amount on May 12, 2020.

In March 2019, she portrayed Helen, opposite Mean Girls co-star, Kyle Selig, in Stephen Sondheim's Saturday Night at Second Stage Theater, as a part of the theater's "Musical Mondays" weekly concert series.

In April 2019 Henningsen partnered with the African Library Project to create a library for St. Catherine’s School in Migori County, Kenya; a few hours away from where Cady Heron (her fictional character from the Broadway production of Mean Girls) lived. She raised money to pay for shipping costs and collected new and used books donated at the stage door of the August Wilson Theatre. In just over a month, Henningsen received over 1,100 donated books and shipped the "library" to Migori County, Kenya.

Henningsen has also participated in events supporting Artists Striving to End Poverty (ASTEP), Artists For Action NYC, Broadway Sings for Immigration Equality, and Broadway Cares/Equity Fights AIDS (BCEFA). In July 2018, she attended the 20th Broadway Barks, an annual event promoting the adoption of shelter animals. In December 2018, Henningsen participated in the second annual Broadway Beats Hunger concert, raising funds for the Summit Medical Group Foundation's "Food, Health and Hope: An Answer to Diabetes" initiative. She was a prominent advocate for the Actors' Equity Association's "Not a Lab Rat" campaign, petitioning for actors participating in developmental labs for new stage productions to have a higher minimum salary and also receive a share of the production's profits.

In February 2017, she appeared in an Off-Broadway staged concert of Jerry Herman's musical, Dear World, as Nina with the York Theatre Company, starring alongside Tyne Daly, Alison Fraser, and Ann Harada.

Henningsen returned to the Pittsburgh Civic Light Opera (PCLO) in the summer of 2017, starring as Sophie in the company's regional production of Mamma Mia!. During her run at PCLO, it was announced that she was cast as Cady Heron in the upcoming Washington, D.C. production of Mean Girls.

Beginning in 2017, Henningsen starred as Cady Heron in the Tony Award-nominated Broadway musical, Mean Girls, written by Tina Fey with music and lyrics by Jeff Richmond and Nell Benjamin, respectively. The show had its world premiere as an out-of-town tryout at the National Theatre in Washington, D.C. from October 31, 2017 to December 3, 2017, in which Henningsen originated the role of Cady Heron. She was later nominated for an Outer Critics Circle Award for this role. The musical, which is based on the film of the same name, began previews on March 12, 2018, and officially opened on Broadway on April 8, 2018 at the August Wilson Theatre in New York City. During the weeks surrounding the Broadway opening of Mean Girls, Henningsen filmed a series of video blogs for Broadway.com entitled "Too Grool for School: Backstage at Mean Girls with Erika Henningsen," giving viewers a look backstage and at events like opening night, the cast album recording, and the cast's appearance on The Today Show. Henningsen left the production on February 22, 2020 and was replaced by actress, Sabrina Carpenter.

In late 2017 Henningsen met and began a relationship with fellow actor, Kyle Selig, while performing opposite him in the out-of-town tryout for Mean Girls in Washington, D.C.

In the summer of 2016, Henningsen portrayed Ensign Nellie Forbush, opposite Ben Davis, in the Pittsburgh Civic Light Opera's production of South Pacific.

In November 2014, she made her New York Philharmonic debut as Kim Ravenal in a staged concert production of Kern and Hammerstein's Show Boat. A live taping of the production later aired on PBS on October 16, 2015.

Henningsen made her Broadway debut as Fantine in the revival of Les Misérables on March 3, 2015. She has disclosed in interviews that she was about to file for unemployment when she learned she was cast as Fantine, which also happened to be the last role she played as an undergraduate at the University of Michigan, 11 months earlier. She is the youngest actress in Broadway history (to date) to portray the role of Fantine. She left the production along with fellow Les Misérables co-stars, Ramin Karimloo and Samantha Hill, on August 30, 2015 and was replaced by Memphis star, Montego Glover.

Later that year, Henningsen starred as Beth in the musical, Diner, based on Barry Levinson’s 1982 film of the same name with music and lyrics by Sheryl Crow. The musical, directed and choreographed by Kathleen Marshall, made its world premiere with a sold-out run at the Signature Theatre in Washington, D.C. from December 9, 2014 to January 25, 2015. She remained part of the production and its extended run when it was staged by the Delaware Theatre Company in December 2015.

She graduated from Campolindo High School in 2010 and then studied at the University of Michigan, earning a BFA in musical theatre in 2014. During her undergraduate, she also studied at the Royal Academy of Dramatic Art in London through the NYU London program. Henningsen was selected as the sole winner of the 2014 Alan Eisenberg Award Scholarship, an award given to a University of Michigan graduating senior to recognize, "outstanding talent and career potential," in musical theatre.

In 2010 at the age of 17, Henningsen was cast in her first professional production as Penny Pingleton in Hairspray at the Woodminster Amphitheater in Oakland, California.
