"Tennis Court" is a song recorded by New Zealand singer-songwriter Lorde. She co-wrote the song with Joel Little, with production handled by the latter. Universal Music Group (UMG) released the song as the second single from her debut studio album Pure Heroine (2013) in Australia and New Zealand on 7 June 2013. On the same day, the label released an extended play (EP) of the same name containing three additional tracks throughout Europe. It combines alternative pop, art pop, and downtempo music over hip hop beats, minimalist synthesisers, and an electronic pulse. Inspired by Lorde's fresh insights into the music industry, the lyrics address her newfound fame and nostalgia for Auckland.
"Tennis Court" received positive reviews from music critics, with some highlighting the song's production and lyrical content. It was a commercial success in Oceania, reaching number one in New Zealand and number 20 in Australia. Elsewhere, the single achieved modest chart success throughout Europe and North America. "Tennis Court" earned platinum certification in Canada and triple platinum certifications in New Zealand and Australia. Joel Kefali directed the song's accompanying music video, a one shot in which Lorde stares at the camera throughout. "Tennis Court" was included on the set list of Lorde's Pure Heroine Tour (2013–14) and Melodrama World Tour (2017–18).
