Kesher Israel, Spanish Colonial Revival synagogue in Georgetown, United States

Kesher Israel, also called the Georgetown Synagogue, is a Modern Orthodox synagogue at 2801 N Street NW. The congregation acquired the N Street premises in 1915 and built the current building there in 1931 on a construction budget of $28,000. It is a contributing property to the Georgetown Historic District, a National Historic Landmark listed on the National Register of Historic Places.

In 1910 six Jewish merchants formed the Georgetown Hebrew Benevolent Society and held services above a storefront on M Street, NW. A year later the group, by then 50 families, founded Kesher Israel Congregation, the city's seventh synagogue. The congregation moved to 2801 N Street, NW, in 1915 and built the present synagogue there in 1931 for $28,000.

The congregation blends Orthodox Jewish traditions with modern life in Washington, D.C., welcoming professionals, students, and families from different backgrounds. The space reflects how religious practices find expression within a diverse urban community.

Kesher Israel stands at 2801 N Street, NW, in Georgetown, a site the congregation has used since 1915. It is the last of the city's original pre-war Orthodox synagogues still within walking distance of downtown Washington; the others moved uptown or to Montgomery County, Maryland, from the 1950s. The building is a contributing property to the Georgetown Historic District.

Senator Joseph Lieberman, a member, was chosen as the Democratic vice-presidential nominee in 2000, drawing national media attention to the synagogue. When the Senate held important votes on Shabbat, he walked nearly 3 miles (5 km) from Kesher Israel to the Capitol, a trek he made over 25 times.
