Reitmans Ltd. is a Canadian retailing company, specializing in women's clothing. The company operated several store brands, including Reitmans, R.W. & Company, Penningtons, Addition-Elle, Thyme Maternity, Cassis, Smart Set and Hyba.

It was founded in 1926 by Herman and Sarah Reitman, in Montreal, Quebec, Canada. The immediate success of the first store on Saint Laurent Boulevard prompted the Reitmans to open a second store which sold exclusively women's clothing. The founders grandsons Jeremy Reitman (who died in 2019) would later serve as chairman of the board and chief executive officer, with his brother Stephen Reitman as president and chief operating officer. By 2016, the company was active in 685 locations with stores in every province and two of three territories in Canada. For the fiscal year of 2015, net earnings were $13,415,000 on sales of $939,376,000. However, Reitmans filed for bankruptcy protection in May 2020 and subsequently closed its Thyme Maternity (54 locations) and Addition Elle (77 locations) stores over the summer of 2020. The company's stock was moved from the Toronto Stock Exchange to the TSX Venture Exchange.

Reitmans' used the motto "Fits your beautiful", changed from Designed for real life. In fall 2004, Reitmans used this slogan to advertise, saying: "Life is a catwalk. Have fun with it!".
