Parviz Tanavoli (Persian: پرویز تناولی; born 1937) is an Iranian sculptor, painter, educator, and art historian.

Since 1989, Tanavoli has held dual nationality and has lived and worked both in Tehran, and Horseshoe Bay in West Vancouver, British Columbia.

Tanavoli's newest "heeches" exhibition, titled "All and Nothing," was held at Tehran's Art Space Gallery from July 6 to August 3, 2022.

[9][10] He is the main figure and the key member of the Saqqakhaneh group of artists who share a common popular aesthetic, according to the scholar Karim Emami.

[5] Composed of three Persian characters in the style of nasta'liq, the three letters he, ye and če are combined to produce the word heech.

[13][14] Rasht 29 Club was named after the street address, and it was a popular hangout amongst artists of the time including Marcos Grigorian, Hossein Zenderoudi, Sadegh Tabrizi, Faramarz Pilaram, Sohrab Sepehri, Massoud Arabshahi, Yadollah Royai, Nader Naderpour, Reza Baraheni, Esmail Shahroudi, Ahmadreza Ahmadi, Bijan Elahi, Ebrahim Golestan, Hageer Daruish, Kamran Shirdel, Sadeq Chubak, Karl Schlamminger, and others.

[14] Tanavoli's work has been auctioned worldwide, leading to over $9 million in overall sales, making him the most expensive living Iranian artist.

[15] In 2008, his work, The Wall (Oh Persepolis), an almost 2-meter tall bronze sculpture covered in incomprehensible hieroglyphs fetched USD 2.84 million at a Dubai Christie's sale, which was an auction record for an artist of Middle Eastern origins.

[citation needed] A day before Tanavoli was due to speak at the British Museum in 2016, authorities in Iran confiscated his passport, preventing him from leaving the country, accusing him of "disturbing the public peace".
