Thomas Duckett Senior or Thomas Duckett I (1804-1878) was an English sculptor
Born in Claughton, Wyre, he was apprenticed to a plasterer before working in Lancaster as a wood carver. Next he was employed by the sculpture firm Franceys and Spence in Liverpool then the architectural and sculptural firm of Francis Webster and Sons in Kendal.
He set up his own studio around 1844 in Preston, Lancashire, with tomb monuments and busts forming most of his output. That town commissioned a statue of Robert Peel from him in 1850, now in Winckley Square in the town, though he failed to win the competitions for Leeds' Wellington Monument and another Peel monument in Bolton, Lancashire. His works are well-represented in Preston's Harris Art Gallery.
He and his wife are both interred in the cemetery in New Hall Lane Cemetery, with a monument that has a head on each elevation, possibly carved or at least designed by Duckett himself. Their son Thomas Duckett Junior was also a sculptor.
