Founded by Maria Bowen Chapin, the Chapin School originally opened in 1901, at 12 West 47th Street as "Miss Chapin's School for Girls and Kindergarten for Boys and Girls" with an enrollment of 78 students and seven teachers. Following a move to East 58th Street in 1905 and a later move to East 57th Street in 1910, the school relocated, in 1928, from Midtown Manhattan to its present location on Manhattan's Upper East Side at 100 East End Avenue at East 84th Street.
The first Chapin diplomas were awarded in 1908; 1917 marked the last year that boys were included in the school. The name was changed to the Chapin School in 1934.
Academics, activities, and athletics
Chapin's 755 students are split into three divisions: Lower School (kindergarten through grade 3), Middle School (grades 4 through 7), and Upper School (grades 8 through 12). About 54 girls start in kindergarten, and that number remains essentially unchanged through 12th grade.
There are 265 girls in the Upper School (8th through 12th grades), where they are taught by 53 faculty members. The curriculum is considered traditionally rigorous with multiple requirements, including at least one modern language and two years of Latin. While fairly small in size, Chapin offers 15 Advanced Placement courses and a total of 36 elective courses in grades 10-12. Many girls do independent studies or study abroad programs, particularly through Chapin's exchange programs with the St. Hilda’s Anglican School for Girls (Perth, Australia) and the American Community Schools (Athens, Greece). Chapin is also a charter affiliate member of the Online School for Girls (OSG), in which students can take courses offered to more than 30 girls’ schools across the country. New York Interschool courses are offered in advanced math, leadership, and ethics. Mentorship derives from multiple sources, including faculty advisors and peer leaders.
While some Chapin girls live on the Upper East Side near the school, others hail from other parts of Manhattan, as well as Brooklyn, Queens, the Bronx and New Jersey. Young women of color make up 38% of the student body. The student-to-teacher ratio is 7 to 1. Twenty-one percent of the girls receive tuition assistance.
While girls can start up their own clubs and activities, there are currently 21 clubs run by students. These include the student government (advisory), the student newspaper, the literary magazine, Amnesty International, the Gay-Straight Alliance, the Model UN, and groups dedicated to the study and performance of Classics, dance, drama, music, math, media, robotics, the environment, and science.
There are 18 athletics teams, including 15 varsity sports in which the Gators compete against similarly-sized schools around New York City. Sports include badminton, basketball, cross country, fencing, field hockey, golf, gymnastics, indoor track, lacrosse, soccer, squash, swimming, tennis, track and volleyball.
The school's motto is Fortiter et Recte (Bravely and Rightly).
The wheel on the school's seal was chosen by Miss Chapin because it is the symbol for Saint Catherine of Alexandria, the patron saint of philosophers, thinkers, and educated women. The students leave assembly in a wheel pattern. 
Chapin has a longstanding tradition of green/gold competitions among middle and upper schoolers. Throughout the year, but especially on the annual field day, these green and gold teams fiercely compete until a winner is announced at the end of each school year. Girls join their team in 4th grade--when applicable, joining the team of their mother or grandmother--and remain on the same team throughout their time at Chapin. 
Chapin has affiliations with a variety of other New York City schools, including Collegiate School and the Spence School but is most closely aligned and rivalrous with the neighboring Brearley School, with which it shares some classes, after-school programs, and a robotics team.
All Chapin programs exist under one roof. The building features the two-story Annenberg library with over 45,000 volumes and rooms for multimedia and video editing.   As of 2015, Chapin featured 49 classrooms, eight science laboratories, four art studios including a photography darkroom and a ceramics studio, two music studios, a black box theater, a dance studio, two computer laboratories, four gymnasiums and a greenhouse.
Chapin girls also make frequent use of Carl Schurz Park, which is located across the street from the school.
Chapin's 2008 construction provided new facilities for art, language, science and the greenhouse via expansion of the fifth and sixth floors and addition of the seventh and eighth floors. 
New construction was begun in May 2015. When it is completed, Chapin will have a regulation-size gymnasium to complement its four current gyms, a rooftop turf practice field and fitness center, expanded performing arts facilities, much larger dining facilities, and additional classrooms to provide more flexibility and experiential learning.
College placement and rankings
Chapin is typically ranked among the top dozen private schools in the United States, with a Wall Street Journal article ranking Chapin's college placement as third best in the country.
"Chapin girls marry doctors. Spence (or Nightingale) girls have affairs with doctors. And Brearley girls become doctors." This saying is no longer true, if ever it was. Chapin girls do many things after graduation, even if two former students did go on to become queens and another became First Lady. Focusing on women who had independent careers, some of the most widely-known alumnae are listed below:
