Anna Sorokin (Russian: Анна Сорокина, romanized: Anna Sorokina, pronounced [ˈanːə sɐˈrokʲɪnɐ]; born January 23, 1991), also known as Anna Delvey, is a con artist and fraudster who posed as a wealthy heiress to access upper-class New York social and art scenes from 2013 to 2017.

Born near Moscow, Delvey emigrated from Russia to Germany with her family at the age of 16 in 2007. In 2011, at the age of 20, Delvey left Germany to live in London and Paris. In 2013, Delvey relocated to New York City, where she interned for the French fashion magazine Purple. She conceived of a private members' club and arts foundation, which included leasing a large building to feature pop-up shops and exhibitions by notable artists she met while interning. She later created fake financial documents to substantiate her claims of having a multi-million-euro trust fund and forged multiple wire transfer confirmations. She used these documents, as well as fraudulent checks, to trick banks, acquaintances, and realtors into paying out cash and granting large loans without collateral. She used this to fund her lavish lifestyle, including residencies in multiple upscale hotels.

Between 2013 and 2017, Delvey defrauded and deceived major financial institutions, banks, hotels, and individuals. In 2017, the NYPD arrested Delvey in a sting operation with the help of her former friend, Rachel DeLoache Williams, who accused Delvey of defrauding her of US$62,000. In 2019, a New York state court convicted Delvey of attempted grand larceny, larceny in the second degree, and theft of services, and she was sentenced to 4 to 12 years in prison. After serving two years, she was released on parole. Six weeks later, she was taken into the custody of U.S. Immigration and Customs Enforcement for deportation to Germany. In October 2022, after 19 months of detention, Delvey was granted a $10,000 bail bond and released to house arrest.

Delvey's story gained publicity when Williams wrote a lengthy article in Vanity Fair about her experiences with Delvey in 2018. She expanded on the story in her book My Friend Anna (2019). The same year, journalist Jessica Pressler wrote an article for New York about Delvey's life as a socialite; Netflix paid Delvey $320,000 for the rights to her story and developed it into the miniseries Inventing Anna (2022). Delvey's life story has been the subject of multiple other television shows, interviews, podcasts, and theater productions.

Delvey was born on January 23, 1991, in Domodedovo, a working-class satellite town south of Moscow, Russian Soviet Federative Socialist Republic, in the Soviet Union. Her father, Vadim, worked as a truck driver and her mother owned a small convenience store. In 2007, when Delvey was 16, her family relocated to North Rhine-Westphalia, Germany. There, her father became an executive at a transport company until the company became insolvent in 2013. He then opened an HVAC business specializing in efficient energy use. Delvey's mother was a housewife. Delvey attended the Bischöfliche Liebfrauenschule Eschweiler (Episcopal School of Our Lady of Eschweiler), a Catholic grammar school in Eschweiler. Peers said she was quiet and struggled with the German language. As a young adult, Delvey obsessively followed Vogue, fashion blogs, and image accounts on LiveJournal and Flickr.

After graduating from the school in June 2011, Delvey moved to London to attend Central Saint Martins, an art school, but soon dropped out and returned to Germany. In 2012, she briefly interned at a public relations company in Berlin. Delvey then relocated to Paris, where she earned around €400 per month at an internship for Purple, a French fashion magazine. Delvey did not contact her parents often, but they subsidized her rent. Around that time, she adopted the "Delvey" surname, which she said was based on her mother's maiden name. Delvey's parents, however, said they do not recognize the surname.

In mid-2013, Delvey traveled to New York City to attend New York Fashion Week. Finding it easier to make friends in New York than Paris, she opted to stay, transferring to Purple's New York office for a brief time. After quitting Purple, Delvey came up with the idea of the "Anna Delvey Foundation"—a private members' club and art foundation—and unsuccessfully sought funding from wealthy members of the city's social scene. Her proposal included leasing the entire Church Missions House, comprising six floors and 45,000 sq ft (4,200 m²) and owned by Aby Rosen's RFR Holdings, as a multipurpose events venue and art studio, where she planned a visual arts center with pop-up shops curated by artist Daniel Arsham, one of her acquaintances from her internship, and exhibitions by Urs Fischer, Damien Hirst, Jeff Koons, and Tracey Emin. She received planning help from the son of architect Santiago Calatrava. She also discussed the sale of drinks at the venue with Roo Rogers.

DJ Elle Dee described a strange encounter with Delvey at a party in May 2014 in Montauk, New York, where Delvey pretended to be a wealthy heiress and bragged about the brands of clothes she was wearing, but also asked partygoers for a place to sleep. After they declined, she slept in a car. Dee also attended another party that Delvey organized at The Standard, High Line saying about the attendees that: "She barely knew them—as if it was maybe the second time they'd ever met, kind of like us. Everyone just sat around, quietly staring at their own phones." Dee called Delvey "entitled and mean," particularly to people in the service industry. She castigated people who did not have many followers on Instagram and bragged that she was going to rent a $12,000-per-month six-bedroom rooftop apartment. Dee also said that Delvey often relied on her and other acquaintances to pay her expenses, claiming she had forgotten her wallet or that it was an emergency and her credit cards did not work, shedding crocodile tears that dried up quickly when she realized the scheme would not work.
