City of Lover was a one-off concert by the American singer-songwriter Taylor Swift held at the Olympia in Paris, France, on September 9, 2019. It happened slightly over two weeks after the release of Swift's seventh studio album, Lover (2019). The concert was reserved for fans who had won tickets through online contests or album purchases. The set list consisted of 16 songs, with eight from Lover and eight from Swift's other albums. City of Lover ran for one hour, and was the only concert that Swift held to promote Lover, after the planned sixth concert tour Lover Fest was canceled due to the COVID-19 pandemic. On May 15, 2020, a television special titled Taylor Swift: City of Lover, filmed at the concert, was broadcast on ABC in the United States. Compared to the original concert, the TV special only included the eight Lover tracks and ran for 42 minutes, including commercials.

City of Lover and its corresponding TV special received positive reviews from media publications, who lauded Swift's stage presence and intimate engagement with fans. However, a few critics complained that the TV special should have included the whole sixteen-song set list instead of just the eight Lover songs. Some publications noted that Swift's concert at the Olympia—a venue with a 2,000-seat capacity—was a rare move for her after her 2018 Reputation Stadium Tour, which sold-out venues with much higher capacities. The TV special was made available on Hulu and Disney+ for a few weeks beginning on May 16, 2020. A live album, titled Lover (Live from Paris) and containing the performances from the special, was released in a Valentine's Day limited-edition vinyl LP on February 14, 2023.
