W. T. Grant or Grants was a United States-based chain of mass-merchandise stores founded by William Thomas Grant that operated from 1906 until 1976. The stores were generally of the variety store format located in downtowns.

In 1906 the first "W. T. Grant Co. 25 Cent Store" opened in Lynn, Massachusetts. Modest profit, coupled with a fast turnover of inventory, caused the stores to grow to almost $100 million annual sales by 1936, the same year that William Thomas Grant started the W. T. Grant Foundation. By the time Grant died in 1972 at age 96, his chain of W. T. Grant Stores had grown to almost 1,200.

Like many national chain stores, Grant arranged for Columbia to create a low price exclusive record label, Diva, sold only at Grants. The label existed from 1925 through 1930.

Grant's stores were slower than the Kresge stores to adapt to the growth of the suburb and the change in shopping habits that this entailed. The attempt to correct this was belated; in the 1960s and early 1970s, the company built many larger stores (later known as Grant City), but unlike Kresge's Kmart they lacked uniform size and layout, so that a shopper in one did not immediately feel "at home" in another. The chain's demise in 1975 was in part due to a failure to adapt to changing times but was probably accelerated by management's refusal until it was too late to eliminate the shareholder dividend. After the company began to lose money, funds were borrowed to pay the quarterly dividend until this became impossible. A final tactic to stay in business involved requiring Grant's clerks and cashiers to offer a Grant's credit card application to customers to boost sales in the stores.

William Thomas "W. T." Cosgrave (Irish: Liam Tomás Mac Cosgair; 6 June 1880 – 16 November 1965), was an Irish politician who succeeded Michael Collins as Chairman of the Irish Provisional Government from August to December 1922. He served as the first President of the Executive Council (prime minister) of the Irish Free State from 1922 to 1932.

William Thomas Cosgrave, W. T., or Liam as he was generally known, was born at 174 James's Street, Dublin in 1880. He was educated at the Christian Brothers School at Malahide Road, Marino, before entering his father's publican business. Cosgrave first became politically active when he attended the first Sinn Féin convention in 1905.

He was a Sinn Féin councillor on Dublin Corporation from 1909 until 1922 and joined the Irish Volunteers in 1913. Cosgrave played an active role in the Easter Rising of 1916 serving under Eamonn Ceannt at the South Dublin Union. Following the rebellion Cosgrave was sentenced to death, however this was later commuted to penal servitude for life and he was interned in Frongoch, Wales. While in prison Cosgrave won a seat for Sinn Féin in the 1917 Kilkenny by-election.
